CHANGELOG.md

Changelog

All notable changes to PHPantom will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Fixed

• Property self/static type resolution. Properties declared with @var self|null or static type annotations now resolve to the owning class name instead of displaying the raw self/static keyword in hover and type inference.
• Magic __get property access. Accessing undefined properties on objects with a __get method now resolves to the method's declared return type, even when __get has no template parameters (e.g. SimpleXMLElement::$child resolves to SimpleXMLElement).
• Magic __call method return type. Calling undefined methods on objects with a __call method now resolves to __call's declared return type for hover and type inference.
• Multi-namespace function return type resolution. In files with multiple namespace { } blocks, function return types were resolved against the first namespace instead of the function's own namespace. This caused incorrect type inference for variables assigned from function calls in later namespace blocks.
• Template inference through stub interfaces. @template-implements on stub-loaded interfaces (e.g. IteratorAggregate<int, Foo>) now correctly propagates substituted return types to child methods that omit a return type annotation. Previously these resolved as untyped.
• Generic method return types from @var annotations. When a variable is annotated with a generic type (e.g. /** @var Collection<int, User> */ $items), method calls on that variable now correctly substitute class-level template parameters into the return type. Previously, return types like TValue remained unsubstituted.
• Short class name resolution in type hints. When resolving an unqualified class name from a property or return type annotation, the resolver now prefers the class in the same namespace as the owning type before falling back to first-match.
• Foreach narrowing with break in else. When a foreach body contained an if with an else { break; } branch, the variable state from the break path was not included in the post-loop type, causing the merged type to be too narrow.
• @var docblocks with additional tags. When a @var annotation shared a docblock with other tags (e.g. @psalm-suppress, @deprecated), the extra lines were included in the type string, corrupting type resolution. Multi-line @var docblocks now correctly extract only the type from the first line.
• Foreach element type from untyped arrays. Variables bound in a foreach over an untyped array (e.g. from a function returning bare array) now resolve to mixed instead of empty, so assignments from the loop variable propagate correctly.
• Foreach target type after non-empty literal array. When iterating a non-empty literal array such as ["a", "b", "c"], the pre-loop sentinel value of the target variable (e.g. null from $tag = null) no longer survives as a possible post-loop type.
• Object cast type inference. (object)$scalar now resolves to object{scalar:T} and (object)$array resolves to an object shape matching the array's keys, instead of bare stdClass.
• Foreach @var annotations for key and value variables. Multi-line docblocks with multiple @var tags before a foreach now correctly override the inferred key and value types. Previously only single-@var docblocks were recognized, and only for the value variable.
• Template union inference from multiple arguments. When multiple arguments bind to the same @template T parameter (e.g. pick($int, $float) or test(B::class, C::class) with @param class-string<T>), the resolved type is now the union of all inferred argument types instead of only the first one.
• Array shape keys with special characters. Array literal keys containing backslashes, newlines, or other non-identifier characters are now properly quoted and escaped in type display (e.g. array{'foo\\bar\nbaz': string} instead of a truncated type string).
• Static method calls on class-string unions. $variable::method() where $variable holds a union of class-strings now resolves through all possible classes and unions their return types.
• Trait self return type resolution through inheritance. When a trait method has return type self, calling it on a subclass now correctly resolves to the class that uses the trait (the declaring class), not the calling subclass. static and $this continue to resolve to the runtime class.
• NoRewindIterator generic resolution. Added stub patch so new NoRewindIterator($generator) propagates the wrapped iterator's type parameters.
• Template param inference from type bounds. When a class template parameter has a bound like TIterator as Iterator<TKey, TValue> and TIterator is resolved to a concrete generic type, the nested template params (TKey, TValue) are now inferred from the concrete type's generic arguments.
• static return type through first-class callables. self::method(...)(), static::method(...)(), parent::method(...)(), and $this->method(...)() now preserve static in the return type when the underlying method declares @return static.
• ArrayAccess array-access assignment. $obj[$key] = $val on objects implementing ArrayAccess no longer overwrites the variable's generic type annotation with an array type.
• Method-level @template with key-of bound. When a method declares @template K as key-of<TData> and returns TData[K], passing a string literal argument (e.g. $config->get('name')) now infers K from the literal and resolves the return type to the specific array shape value type.
• @template T as Bound parsing. Template declarations using the as keyword (e.g. @template T as SomeClass) now correctly parse the upper bound. Previously only of was recognized, causing as bounds to silently fall back to mixed.
• __get template return type substitution. Dynamic property access on generic classes with a __get method now correctly substitutes class-level template parameters. Previously __get was resolved against the raw class, ignoring constructor-inferred type arguments.
• Intersection type method return. Method calls on intersection types (e.g. IChild&IParent<C>) no longer include mixed from unparameterized members when a parameterized member provides a concrete return type.
• Property narrowing after guard clauses. After if (!$this->prop instanceof Foo) { return; }, the narrowed type of $this->prop was being stripped before subsequent code could use it. Member accesses on the narrowed property (e.g. in a foreach) now resolve correctly.

Changed

• Updated embedded phpstorm-stubs. Generic annotations for ArrayIterator, ArrayObject, SplDoublyLinkedList, SplQueue, SplStack, SplPriorityQueue, SplFixedArray, SplObjectStorage, and array_reduce are now provided by upstream stubs directly, removing the need for runtime patches.

Added

• Argument type mismatch diagnostics. Flags function and method calls where an argument's resolved type is incompatible with the declared parameter type.
• Invalid class-like kind diagnostics. Flags class-like names used in positions where their kind is guaranteed to fail at runtime: new on abstract classes, interfaces, traits, or enums; extends on a final class, interface, or trait; implements with a non-interface; trait use with a non-trait; instanceof with a trait (always false); catch with a non-Throwable type or trait; and traits in native type-hint positions.
• Unused variable diagnostics. Variables assigned but never read are flagged with hint severity and rendered as dimmed text. Covers local variables, foreach key/value bindings, catch variables, and closure use bindings. Variables named $_ or prefixed with $_ are exempt.
• Mago diagnostic proxy. Mago lint and analyze diagnostics are surfaced as LSP diagnostics with quick-fix code actions. Configurable under [mago] in .phpantom.toml. Requires Mago 1.15+.
• PHPCS diagnostic proxy. PHP_CodeSniffer violations are surfaced as LSP diagnostics with sniff-name diagnostic codes and severity mapping. Configurable under [phpcs] in .phpantom.toml.
• Laravel config and env key navigation. "Go to Definition" and "Find All References" now work for string-literal config keys and env variables (config('app.name'), Config::get(...), config()->string(...), env('APP_KEY')). Covers the Config facade, the config() helper (including fully-qualified \config()), and all typed accessors (string, integer, float, boolean, array, collection, set, prepend, push). Contributed by @MingJen in #93 and #96.
• Namespace renaming. Renaming a namespace segment updates all namespace declarations, use statements, group use declarations, and fully-qualified name references across the workspace. When a PSR-4 autoload mapping exists, the corresponding directory is moved to keep the filesystem consistent.
• Linked editing ranges. Place the cursor on a variable and all occurrences within its definition region enter linked editing mode. Typing a new name updates every occurrence simultaneously.
• Import all missing classes. A bulk code action that imports every unresolved class name in the file at once. Only names with a single unambiguous candidate are imported; ambiguous names are left for manual resolution.
• Context-aware import candidate filtering. Import class actions now filter candidates by syntactic context (only interfaces after implements, only traits after use, etc.).
• Convert to instance variable. A code action that promotes a local variable inside a method to a class property, rewriting all references to $this->prop (or self::$prop in static methods).
• Closure and arrow function inlay hints. When a closure or arrow function is passed to a callable-typed parameter, inlay hints show inferred parameter types and the return type. Types are derived from the enclosing callable signature with generic substitution from sibling arguments.
• Return type inference from method bodies. Methods without a declared return type or @return docblock now have their return type inferred from return statements, improving completion, hover, and diagnostics for untyped code.
• Untyped property type inference from constructor. Properties without type declarations are resolved by inspecting the constructor body for assignments and promoted parameter defaults. PHPDoc generation uses the inferred type. Contributed by @lucasacoutinho in #81.
• Binary expression type inference. Hover and variable resolution now show result types for all binary operators with operand-type-aware arithmetic (int + int → int, int + float → float, int / int → int|float). Concatenation returns string, comparison and logical return bool, bitwise returns int (or string when both operands are strings), spaceship returns int, and + distinguishes array union from numeric addition. Compound assignments (/=, *=, %=, **=, .=, <<=, &=, |=, ^=, ??=) update the variable's type with the same operand-aware rules. Incrementing a numeric string literal ($a = "123"; $a++) produces int|float. Parenthesized binary expressions resolve correctly through the structural inference path.
• array_reduce, array_sum, and array_product return type inference. array_reduce() resolves to the type of its initial value argument. array_sum() and array_product() resolve to int|float.
• global keyword variable resolution. Variables imported with global $var now resolve to their top-level type, enabling completion, hover, and go-to-definition.
• Nested array shape inference from multi-level key assignments. Assignments like $b['a']['b'] = 'x' now produce a nested array shape type (array{a: array{b: string}}), enabling array key completion for arrays built incrementally with nested keys.
• Machine-readable CLI output. Both analyze and fix accept a --format flag with table, github, and json options. When GITHUB_ACTIONS is set, table output automatically includes GitHub annotations.
• Generics. @mixin tags referencing a template parameter now resolve through the template bound. new $var() where $var is class-string<T> resolves to T. SPL collection classes (ArrayIterator, SplQueue, WeakMap, etc.) now carry @template parameters so ->current() and ->key() resolve to concrete type arguments.
• PHPStan assertType test runner. A data-driven harness imports PHPStan's assertType() test corpus to validate type inference against the gold standard. Twenty-six test files imported covering narrowing, generics, shapes, enums, and more.

Fixed

• __get magic method template resolution. Property access on a class whose __get uses method-level @template with key-of<T> bounds and T[K] return types now infers the concrete type from the property name. For example, $bag->a on a DataBag<array{a: int, b: string}> resolves to int.

• (object) cast type inference. Casting a scalar to object now resolves to object{scalar: <type>} and casting a typed array shape resolves to an object shape with matching properties.

• Interface method return type inheritance. When a class implements a same-file interface with @implements Interface<ConcreteType> and overrides a method without a return type, the interface method's template-substituted return type is now propagated.

• Class loader global fallback. Unqualified class names used in namespaced code without a use statement (e.g. implements IteratorAggregate in namespace App) now fall back to global scope lookup when the namespace-qualified name doesn't exist.

• Literal true/false preserved in template inference. Passing true or false to a generic constructor now keeps the precise type as the template argument (e.g. C<false>) instead of widening to bool.

• @psalm-method overrides @method. When a class has both @method int foo() and @psalm-method string foo(), the vendor-prefixed tag now takes priority instead of using whichever appeared first in the docblock.

• Multi-namespace class resolution. In files with multiple namespace blocks, short class names now resolve against the correct namespace for the current scope instead of picking the first same-named class in the file.

• False-positive diagnostics on startup. Files opened while the project was still indexing could produce hundreds of spurious "class not found" and "function not found" errors. Diagnostics are now deferred until initialization completes.

• Chained instantiation preserves constructor-inferred generics. Expressions like (new Box(new Product()))->get() and new Box(new Product())->get() now propagate template arguments inferred from constructor parameters to subsequent method calls, so get() returns the concrete type instead of mixed.

• @method tag resolution. Colon return type syntax (@method foo(): bool), parenthesised return types (@method (callable():string) foo(), @method (string|int)[] bar()), and the ambiguous single-static pattern (@method static getStatic()) are now parsed correctly. Template parameters in @method return types are substituted through @extends and @implements annotations (e.g. @method T get() on a parent class resolves to the concrete type when a child declares @extends Parent<string>). $this return types on @method tags preserve generic arguments (e.g. A<B> when the receiver is A<B>).

• First-class callable invocation return types. Immediately invoking a first-class callable (Foo::method(...)(), $this->method(...)(), self::method(...)(), static::method(...)(), parent::method(...)(), func(...)()) now resolves to the underlying method or function's return type. Previously these expressions returned no type.

• isset() and empty() narrowing. isset($x) in a condition now strips null from the variable's type in the truthy branch (matching $x !== null semantics). !isset($x) narrows to null only. !empty($x) strips null from nullable types (e.g. string|null narrows to string). Both simple variables and property access ($obj->prop) are supported, and multiple arguments (isset($a, $b)) narrow all listed variables. Guard clauses (if (!isset($x)) { return; }) strip null from the variable in the code that follows.

• Hover scales linearly on large files. Processing many hover requests on the same file (e.g. a test suite with 80+ assertion calls) no longer takes O(n²) time. The first hover on a method body walks it once and caches scope snapshots; every subsequent hover on the same file content is an O(log n) lookup with no re-walk.

• @return numeric pseudo-type. Functions annotated with @return numeric now resolve to the numeric pseudo-type instead of string. Arithmetic on numeric operands correctly infers int|float, and $a++ on a numeric variable yields int|float. The underlying cause was that same-file function calls in multi-namespace files fell through to an incorrect fallback when the file-level namespace differed from the function's namespace.

• parent::__construct() with @extends generics. Calling parent::__construct($arg) in a child class that specifies @extends Parent<Concrete> no longer produces false-positive type errors for the substituted parameter types.

• Array access on bare array and mixed types. Accessing a key on a parameter typed as plain array (e.g. $params['key']) now resolves to mixed instead of an empty type, eliminating false-positive type errors downstream (e.g. $x = $params['key'] ?? null followed by an is_string() guard).

• Analyzer and LSP no longer hang on files with deeply nested loops. Files with multiple levels of foreach/while/for inside if-branches no longer cause exponential blowup.

• Non-deterministic diagnostic counts eliminated. Projects with heavy use of method-level @template no longer see spurious false positives that vary between runs due to cache contamination by concrete type arguments.

• Pull-diagnostic reliability. Editors like Zed that support pull diagnostics no longer show duplicate diagnostics, no longer get stuck with stale results after edits, and now display all diagnostics on first file open without requiring an edit to trigger them.

• Infinite loop on array key reassignment patterns. Files containing $arr['key'] = f($arr['key']) or similar read-then-write patterns on the same array key no longer hang the analyzer.

• Stack overflow on large codebases and large files. The analyze command and files with hundreds of class definitions no longer crash with stack overflows.

• analyze and fix commands run at consistent speed regardless of invocation style. Running from within a project directory is no longer ~8x slower than using --project-root.

• Type narrowing. Comprehensive fixes to type narrowing: non-exiting if branches no longer leak narrowed types into post-merge scope; is_float(), is_null(), and other is_*() guards correctly narrow multi-member unions; negated instanceof on nullable unions preserves null; is_object() narrows to all class types in a union (not just the first); instanceof on mixed or object narrows to the checked type; === null and == null narrow to null in the truthy branch; assert($x instanceof Foo) followed by any if block no longer loses the narrowed type; falsy guard clauses strip both false and null; template-constrained types are expanded before guard filtering. is_numeric(), is_bool(), and is_scalar() guard clauses now narrow union types correctly. exit and die are recognized as unconditional exits for guard clause narrowing. Property access expressions ($a->foo) are now narrowed through chained if/elseif/else conditions using is_string(), instanceof, and other type guards. Array shape keys are now narrowed through null-check guard clauses and conditional reassignment (e.g. $a["test"] resolves to int instead of ?int after if ($a["test"] === null) { return; }). After instanceof check plus reassignment inside the if-body, the post-merge type collapses to the common parent class instead of producing a redundant Child|Parent union. Property access after OR'd instanceof checks ($a instanceof B || $a instanceof C) now resolves to the union of all branches' property types. After while and do-while loops exit, the loop condition's inverse is applied to narrow variable types (e.g. do { $a = $a->next; } while ($a) narrows $a to null after the loop; while ($a instanceof Foo) narrows $a to the excluded type after exit). Branch merging no longer loses nullable information when two branches produce the same class with different nullability (e.g. merging A with A|null correctly yields A|null instead of silently dropping the null).

• Mixin resolution. Static method calls on instances of a class with @mixin now resolve through the mixin. @method and @property tags declared on a mixin class are propagated to the consuming class. $this return types on mixin methods resolve to the consumer class. IteratorIterator is now patched with @template parameters and @mixin TIterator (matching PHPStan's stubs).

• Generics. Constructor generic inference now works through inherited constructors: child classes without their own constructor infer template parameters from the parent's constructor arguments, with correct remapping through multi-level @extends chains (including swapped or renamed template parameters). Function-level @template parameters bound to generic wrapper types (e.g. @param Container<TItem> $c) are inferred from arguments that extend the wrapper class. Method calls are now case-insensitive, matching PHP semantics (e.g. $obj->getId() finds getID()). Closure literals passed to @template parameters are recognised as Closure. Class-level template parameters are preserved through chained method calls. Template parameters fall back to their declared bound (or mixed when unbounded) when subclasses omit @extends or @use annotations. Unbound template parameters at call sites resolve to their declared bounds or mixed instead of leaking raw names. Method-level templates resolve correctly through generic wrappers and nested call chains. Return type generic arguments are preserved for template substitution, fixing false "expects TRelatedModel, got Translation" diagnostics. Iterating over a subclass that extends a generic collection with scalar type arguments (e.g. IntCollection extends Collection<int, int>) now yields the concrete scalar type instead of the raw template parameter name. Calling a method on a union of generic types (e.g. $var->get() where $var is C<A>|C<B>) now resolves to the union of each branch's return type (A|B) instead of only the first branch. Empty array literals passed to generic constructors or functions infer never for element type parameters (e.g. new ArrayCollection([]) resolves to ArrayCollection<never, never>).

• Type narrowing. Comprehensive fixes to type narrowing: non-exiting if branches no longer leak narrowed types into post-merge scope; is_float(), is_null(), and other is_*() guards correctly narrow multi-member unions; negated instanceof on nullable unions preserves null; is_object() narrows to all class types in a union (not just the first); instanceof on mixed or object narrows to the checked type; === null and == null narrow to null in the truthy branch; assert($x instanceof Foo) followed by any if block no longer loses the narrowed type; falsy guard clauses strip both false and null; template-constrained types are expanded before guard filtering. is_numeric(), is_bool(), and is_scalar() guard clauses now narrow union types correctly. exit and die are recognized as unconditional exits for guard clause narrowing. Property access expressions ($a->foo) are now narrowed through chained if/elseif/else conditions using is_string(), instanceof, and other type guards. Array shape keys are now narrowed through null-check guard clauses and conditional reassignment (e.g. $a["test"] resolves to int instead of ?int after if ($a["test"] === null) { return; }). After instanceof check plus reassignment inside the if-body, the post-merge type collapses to the common parent class instead of producing a redundant Child|Parent union.

• Generics. Constructor generic inference now works through inherited constructors: child classes without their own constructor infer template parameters from the parent's constructor arguments, with correct remapping through multi-level @extends chains (including swapped or renamed template parameters). Function-level @template parameters bound to generic wrapper types (e.g. @param Container<TItem> $c) are inferred from arguments that extend the wrapper class. Method calls are now case-insensitive, matching PHP semantics (e.g. $obj->getId() finds getID()). Closure literals passed to @template parameters are recognised as Closure. Class-level template parameters are preserved through chained method calls. Template parameters fall back to their declared bound (or mixed when unbounded) when subclasses omit @extends or @use annotations. Unbound template parameters at call sites resolve to their declared bounds or mixed instead of leaking raw names. Method-level templates resolve correctly through generic wrappers and nested call chains. Return type generic arguments are preserved for template substitution, fixing false "expects TRelatedModel, got Translation" diagnostics. Iterating over a subclass that extends a generic collection with scalar type arguments (e.g. IntCollection extends Collection<int, int>) now yields the concrete scalar type instead of the raw template parameter name. Calling a method on a union of generic types (e.g. $var->get() where $var is C<A>|C<B>) now resolves to the union of each branch's return type (A|B) instead of only the first branch. Empty array literals passed to generic constructors or functions infer never for element type parameters (e.g. new ArrayCollection([]) resolves to ArrayCollection<never, never>). Array literal arguments to @param array<TKey, TValue> constructor parameters now infer key and value types separately (e.g. ["a" => new Foo()] infers TKey=string, TValue=Foo). key-of<T>, value-of<T>, and indexed access types (T[K]) now evaluate to concrete types after template substitution (e.g. value-of<array{name: string, user: User}> resolves to string|User).

• Vendor functions and constants. Functions and constants defined in vendor packages are now indexed at startup, eliminating false-positive "Function not found" diagnostics.

• Use-imported classes no longer shadowed by global-namespace stubs. The use-map is now checked first for unqualified names, fixing Laravel Facade static method resolution.

• Same-name class in a different namespace no longer shadows inherited members. Parent resolution no longer picks up a same-named class from the current namespace instead of the intended global-namespace parent.

• Short-name collisions eliminated project-wide. Two unrelated classes sharing a short name are no longer treated as identical across diagnostics, go-to-implementation, and trait conflict resolution.

• Transitive interface inheritance. A class implementing an interface that extends another interface is now correctly recognized as a subtype of the parent interface.

• Conditional return types with concrete class-string bounds. Methods with conditional return types now check whether the argument class actually implements the bound interface before choosing the return branch.

• Conditional return type names resolved across files. Class names in conditional type annotations are now resolved through the defining file's use statements.

• Promoted properties. Inline /** @var */ annotations on promoted constructor properties now resolve inside the constructor body and take precedence over @param tags.

• Backed enums. Accessing ->value on a backed enum resolves to the specific backing type (string or int). @implements generics on enums are resolved correctly.

• Class constants. Inherited constants accessed via self::CONST or ChildClass::CONST resolve correctly through multi-level inheritance chains.

• Hover / type display. T[] displays as array<T>, mixed[] as array. PHPDoc type aliases and case-insensitive keywords are normalized to canonical PHP forms. Methods returning parent resolve to the actual parent class name.

• Chain assignments. $a = $b = new Foo() resolves all variables in the chain to the correct type.

• Destructuring. Array destructuring ([$a, $b] = $expr, list(), keyed shapes, nested patterns) and foreach destructuring now resolve types for all destructured variables.

• Hover on generics. Variables assigned from method calls on classes with @implements Interface<ConcreteType> show the substituted return type. Hovering over methods inherited from generic traits shows concrete return types instead of raw template names.

• Variable type resolution. Short class names from @var, @param, and new ClassName() are now resolved to FQN before entering the type pipeline. Template parameter bounds are also resolved through use statements.

• Closure inlay hints. Template parameters in callable signatures are substituted with concrete types inferred from sibling arguments.

• Laravel scopes. Public methods with the #[Scope] attribute are no longer treated as scopes (Laravel requires them to be protected).

• Property narrowing after guard clauses. if (!$this->prop instanceof Foo) { return; } now narrows $this->prop to Foo in subsequent code.

• Static methods. $this no longer resolves inside static methods.

• Hover cache invalidation. Editing a cross-file class's docblock now correctly invalidates the cache so hover immediately reflects updated content.

• CLI with relative paths. Relative paths are canonicalized before building URIs, fixing cross-file resolution when the workspace root is relative.

• Performance. Namespace-qualified scalar type keywords are short-circuited before class resolution, eliminating thousands of wasted lookups per analysis run.

• Foreach over nested generic array access. Iterating over expressions like $this->rules[$key] where the property is typed array<string, list<Rule>> now correctly infers element types.

• Foreach key variable type from static properties and scalar keys. Static property access resolves through property type hints, and scalar key types are extracted from generic iterables.

• Foreach loop prescan no longer leaks reassigned types into same-statement RHS. The loop-body prescan results are deferred until after the normal body walk.

• Foreach by-reference binding. foreach ($array as &$value) no longer triggers false-positive undefined/unused variable diagnostics.

• Foreach iterable type alias expansion. Foreach loops over @phpstan-type aliases resolve the element type correctly.

• Array shape key completion through conditional branches. Keys added inside if blocks are now available for completion after the branch.

• Loop-carried assignments visible during completion. Variables assigned later in a loop body are now discovered during completion inside the same loop.

• Variable completion inside assignment RHS sees the pre-assignment type. The variable retains its previous type when the cursor is inside the right-hand side of a reassignment.

• Scope leakage after closures in chained method calls. Variables from the enclosing method are no longer invisible after a closure argument in a chained call.

• Docblock @param annotations no longer leak across sibling methods or closures. The docblock scanner stops at function boundaries and verifies annotations are attached to their closure.

• class-string<T> parameter completion. Parameters typed as class-string<T> with a bounded template resolve to the bound class. Static member access like $class::KEY finds members on the bound.

• Inherited parameter types propagate to child methods. When a child method overrides a parent without its own @param docblock, the parent's type annotation is used for completion.

• @phpstan-assert-if-false self no longer narrows to the enclosing class. Guard clauses now narrow against the declaring class.

• Unresolvable instanceof target no longer causes false diagnostics. The variable's type is cleared rather than keeping the pre-narrowing type.

• False positive type error for closures passed to callable parameters. \Closure is now recognised as a subtype of callable in argument type checking.

• Union-typed method calls no longer lose resolution on second occurrence. Repeated calls on union-typed variables resolve correctly instead of returning stale cache entries.

• Fluent method chains in namespaced classes. Methods returning static or self resolve correctly across namespaces.

• False-positive undefined variable for by-reference parameters. Passing an undefined variable to a by-reference parameter no longer produces false diagnostics in namespaced code, inherited static methods, or constructors.

• False-positive undefined variable on nested array access assignment. $b['a']['a'] = 'a' no longer flags $b as undefined.

• Missing blank line between namespace and first import. Auto-imported use statements now get a preceding blank line when needed (PSR-12 convention).

• "Remove all unused imports" missing in braced namespaces. The bulk action now appears inside namespace Foo { ... } blocks.

• Exception types in catch clauses matched incorrectly across namespaces. Thrown exception types are now matched regardless of whether short or fully-qualified names are used.

• Nested match(true) expressions. Multiple match(true) expressions sharing narrowed variable names no longer produce incorrect diagnostics.

• Lowercase built-in class names recognized as subtypes of object. PHP classes with lowercase names (e.g. finfo, stdClass) are now correctly treated as class-like in subtype checks.

• Variables prefixed with $this receiving stale type information. Variables like $thisItem no longer receive type information from $this-related narrowing.

• False "class not found" for global-namespace classes loaded via Composer's files autoloading. Classes autoloaded through Composer's files directive are now resolved correctly.

• False-positive type errors on generic class methods and templated static methods. Class-level and method-level @template parameters are now substituted into method parameter types before checking argument compatibility.

Changed

• Lower memory usage for variable type tracking. Scope snapshots used by the forward variable resolver now use interned strings for variable name keys, eliminating redundant heap allocations when cloning scope state at each statement boundary.
• Diagnostic delivery model reworked for pull/push coexistence. Editors that support pull diagnostics now get diagnostics on first file open without waiting for a debounce timer. Each diagnostic source caches results independently, and updates from external tools no longer re-run the entire native diagnostic pipeline.
• Rewritten variable resolver. Variable type resolution now uses a single top-to-bottom pass through each function body with zero recursion and no depth limit.
• Broader type narrowing. instanceof, type-guard functions, in_array() strict mode, assert(), @phpstan-assert-if-true/-if-false, and compound &&/|| conditions now narrow types in if/else branches, guard clauses, while-loop bodies, ternary expressions, and match(true) arms.
• Chain resolution cache. The per-request chain resolution cache is now active for all LSP handlers, not just diagnostics.
• Closure and arrow function parameter inference. Untyped closure parameters are inferred from the enclosing call's callable signature, including through method chains that return static. Generic type substitution flows through to inferred parameters.
• Editing responsiveness. Classes evicted from the cache after a file edit are now eagerly re-populated in dependency order.
• Virtual member resolution. Virtual member providers (PHPDoc mixins, Laravel model, Eloquent Builder) now resolve completely on every class, eliminating cases where mixins or accessors were missing after edits.
• Faster analysis. Analysis time cut significantly on large projects through interning, O(1) method lookup, shared metadata, and reduced redundant work.
• Loop type propagation. Replaced the fixed two-pass loop strategy with assignment-depth-bounded iteration with fixed-point early exit. Variables assigned late in loop bodies are now visible from the start on subsequent iterations.

0.7.0 - 2026-04-08

Added

• @psalm-return, @psalm-param, and @psalm-var tag support. Psalm-prefixed docblock tags are now recognized alongside their PHPStan equivalents for return types, parameter types, variable types, conditional return types, template parameter bindings, and semantic token highlighting.
• Refactoring code actions. Extract function, extract method, extract variable, extract constant, inline variable, promote constructor parameter, generate constructor (traditional and promoted), generate getter/setter, and generate property hooks (PHP 8.4+). Deferred computation ensures the lightbulb menu appears instantly; edit generation only runs when the user picks an action.
• PHPStan quickfixes. Automated fixes for a wide range of PHPStan diagnostics: update or remove mismatched @return/@param/@var tags, remove unused return type union members, fix unsafe new static() (add @phpstan-consistent-constructor, final class, or final constructor), add or remove #[Override], add #[\ReturnTypeWillChange], fix void return mismatches, add inferred iterable return types, remove unreachable statements, remove always-true assert() calls, fix overriding member visibility, fix vendor-prefixed class names, and simplify ternary expressions to ?? or ?->. All quickfixes eagerly clear their diagnostic on apply.
• fix CLI subcommand. phpantom_lsp fix applies automated code fixes across a project. Specify rules with --rule (multiple allowed) or omit to run all preferred fixers. --dry-run reports what would change without writing files. The first shipped rule, unused_import, removes unused use statements project-wide, collapsing blank lines left behind by removals (contributed by @calebdw in #54). Supports path filtering and single-file mode.
• Keyword completions. Context-aware PHP keyword suggestions filtered by scope (e.g. return only inside functions, break only inside loops, member keywords inside class bodies, enum backing types after enum Name:). Contributed by @ryangjchandler in #43.
• Attribute completion. Typing inside #[…] offers only classes decorated with #[\Attribute], filtered by the target declaration kind.
• Eloquent model enhancements. Timestamp properties (created_at, updated_at) are automatically typed as Carbon with support for $timestamps = false and custom column constants. Legacy $dates arrays produce typed virtual properties. $appends entries produce virtual properties. where{PropertyName}() dynamic methods are synthesized from all known columns (including @property annotations) on both the model and the Builder. whereHas/whereDoesntHave closure parameters resolve to Builder<RelatedModel> by traversing relationship methods, with dot-notation chain support. Conditionable::when()/unless() chains preserve type information.
• Type-guard narrowing. is_array(), is_string(), is_int(), is_float(), is_bool(), is_object(), is_numeric(), and is_callable() narrow union types inside if/else/elseif bodies and after guard clauses, preserving generic element types through narrowing.
• Array value type tracking. Arrays built incrementally with variable keys inside loops now carry element types through foreach iteration, bracket access, and null-coalescing. Foreach over generic arrays with non-class element types (array shapes, scalars) now preserves the full element type.
• Inherited docblock type propagation. When a child class overrides a method without providing its own @return or @param docblock, the ancestor's richer types flow through automatically. Applies to return types, parameter types (matched by position), property type hints, and descriptions.
• Bidirectional template inference from closures. Templates appearing in callable parameter signatures are now inferred from both the closure's return type and its parameter types. Positional matching is supported, and return-type bindings take priority when the same template appears in both positions.
• Drupal project support. Drupal projects are detected via composer.json. Drupal-specific directories and PHP extensions (.module, .install, .theme, .profile, .inc, .engine) are recognized and indexed. Contributed by @syntlyx in #52.
• Completion and signature help for new self, new static, and new parent. Constructor parameter snippets and signature help inside the parentheses. Contributed by @RemcoSmitsDev in #51.
• Hover on parameter variables at their definition site. Hovering on a function or method parameter now shows its resolved type, using the @param docblock type when it is richer than the native hint. Contributed by @RemcoSmitsDev in #68.
• Array element type extraction from property generics. Bracket access on properties annotated with generic array or collection types (e.g. $this->cache[$key]->) now resolves the element type correctly through nested chains, string-literal keys, and method chains after the bracket.
• @phpstan-assert-if-true $this narrowing. Instance methods annotated with @phpstan-assert-if-true or @phpstan-assert-if-false targeting $this now narrow the receiver variable in the corresponding branch. Contributed by @syntlyx in #52.
• Namespace completion from file path. When creating a new PHP file, typing namespace suggests the correct namespace inferred from the file's location and the project's PSR-4 autoload mappings. The most specific mapping is preselected so you can accept it with a single keypress. When multiple PSR-4 roots match the same directory, all candidates appear ranked by specificity (longest match first).
• Standalone @var docblock for untyped closure parameters. When a closure parameter lacks a type hint and no assignment follows, a @var block above the usage is now picked up as the variable's type.
• --stdio CLI flag. Accepted (and ignored) for compatibility with LSP client wrappers that pass --stdio by default. Contributed by @markkimsal in #67.
• --tcp CLI flag. phpantom_lsp --tcp 9257 starts the server listening on a TCP port instead of stdin/stdout. Useful for debugging or connecting from IDE plugins that prefer a network transport over spawning a child process. Accepts a full address (127.0.0.1:9257) or just a port number. The server accepts one connection and exits when the client disconnects.
• Zed extension setup instructions. Contributed by @daronspence in #47.
• SETUP.md improvements. Contributed by @mattsches in #61.
• Method-level template parameters resolve inside method bodies. @template T of Builder with @param T $query now resolves $query to the template bound inside the method body, providing completions from the bound class.
• Undefined variable diagnostic. Variable reads that have no prior definition (assignment, parameter, foreach binding, catch variable, global, static, use() clause, or destructuring) in the same scope are flagged as errors. Writes must appear before the read in source order, catching use-before-assign bugs, while assignments inside branches (if/else, switch, try/catch) still count to avoid false positives. Suppressed for superglobals, isset()/empty() guards, compact() references, extract() calls, variable variables ($$), @ error suppression, and @var annotations. Static property accesses (self::$prop, static::$prop, parent::$prop) are excluded. Variables passed to by-reference parameters are recognized as definitions: 40+ built-in PHP functions are covered (regex, cURL, OpenSSL, sockets, DNS, etc.), and user-defined functions, static methods, and constructors with &$param parameters are detected automatically from their signatures. Scoping is tracked through arbitrary nesting of closures, arrow functions, and catch blocks. Top-level code outside functions is skipped.
• By-reference parameter type inference for method, static, and constructor calls. When a variable is passed to a by-reference parameter with a type hint (e.g. function foo(Baz &$bar)), the variable acquires that type after the call. Previously this only worked for standalone function calls. Now it also works for $this->method(), static method calls, and constructor calls.

Changed

• Fewer false-positive diagnostics. Variable resolution now produces the same result across completions, hover, and diagnostics, eliminating cases where diagnostics disagreed about a variable's type.
• @phpstan-ignore is never the preferred quickfix. The "Ignore PHPStan error" code action is explicitly non-preferred, so editor keyboard shortcuts no longer accidentally apply it when another fix is available.
• Generate PHPDoc infers @return from the function body. Typing /** above a function that returns array now produces a specific element type (e.g. @return list<string>) instead of @return array<mixed>.
• Faster startup. Stub loading during initialization is significantly faster.
• More accurate generics resolution. Type substitution and resolution for complex nested generic types is more correct, particularly for unions, intersections, array shapes, and deeply nested generic arguments.
• More accurate type predicates. NULL, Null, and case variants of null are now handled consistently throughout type checking, matching PHP's case-insensitive treatment of type keywords.
• Go-to-definition at declaration sites returns the symbol's own location. Class, member, and variable declaration names now return their own location instead of nothing, so editors that detect "definition == cursor" can automatically fall back to Find References. Contributed by @lucasacoutinho in #76.

Fixed

• Completion no longer triggers on the <?php open tag. Typing <?php and pressing enter no longer applies a spurious function suggestion like php_ini_loaded_file().
• Case-insensitive parent handling in chained static calls. resolve_lhs_to_class now handles parent::method(...) in chained callable expressions and uses case-insensitive matching for self/static in the same context.
• Intersection types preserved through resolution. Variables and parameters with intersection types (e.g. Countable&Serializable) now display correctly in hover, extract-function parameter hints, and generated docblocks. Previously intersection types were flattened to unions (Countable|Serializable).
• Return types now carry class info through the resolution pipeline. Method and function return types that name a class (e.g. Collection<User>) now populate the resolved class info eagerly, so downstream consumers (hover, narrowing, completion) no longer need a second resolution pass.
• Generic parameters preserved on resolved types. Catch clause variables, pass-by-reference parameters, closure parameters, and constructor calls now thread the original type hint (including generic parameters) through the resolution pipeline instead of discarding it.
• Type-guard narrowing no longer drops class info on unions. Narrowing a union like Foobar|string|int with is_string()/is_int() in elseif chains now correctly preserves class info for the remaining class member.
• False-positive undefined-variable diagnostic on static property access. self::$prop, static::$prop, and ClassName::$prop no longer trigger an undefined variable warning. Dynamic forms (self::$$prop, self::${expr}) still correctly flag undefined variables used in the expression. Contributed by @lucasacoutinho in #75.
• Case-insensitive self, static, and parent resolution. SELF::method(), Static::create(), PARENT::foo(), and other non-lowercase spellings now resolve correctly. Previously only the exact lowercase forms were recognized.
• Property type resolution in call arguments. When a method argument is $this->prop and the property has a generic, nullable, or union type, the full type structure is now preserved. Previously only the base class name was extracted, discarding generics and union components.
• Update docblock enrichment comparison. The "Update docblock" code action now uses structural type comparison instead of string equality when deciding whether a @param type needs enrichment. Types that are semantically equivalent but formatted differently (e.g. \App\User vs App\User) no longer trigger spurious updates. Body-based @return enrichment now correctly detects when an existing @return tag already has type structure, instead of always proposing a replacement.
• @phpstan-assert and @psalm-assert tags with generic types. Assertions like @phpstan-assert Collection<int, User> $param now parse the full generic type instead of truncating at the first space inside angle brackets.
• parent::method() resolution in inline arguments. Passing parent::method() as an argument to a function now resolves the return type correctly, matching the existing handling for self:: and static::.
• Laravel Eloquent Builder and Collection type resolution. Generic and nullable types on Eloquent models (e.g. Collection<int, User>, ?User) now resolve correctly when used for Builder scope injection, custom collection swapping, and relationship chain inference. Previously these types were stringified with their generic parameters or nullable prefix, causing lookups to fail silently.
• Docblock generation no longer panics on lines with multibyte characters. Files containing non-ASCII characters (e.g. accented letters) could cause the /** docblock trigger to crash or produce misaligned edits due to a mismatch between UTF-16 column offsets and byte offsets.
• Conditional return types showing mixed in hover. When a method with a conditional return type (e.g. @phpstan-return ($type is class-string<T> ? T : mixed)) resolved to a concrete class, hover still displayed the method's declared return type (mixed) instead of the resolved class. Affects methods like Symfony's SerializerInterface::deserialize().
• Method-level @throws types now resolve short names to FQN. Exception types in @throws tags on class methods are now fully qualified using the file's use imports, matching the behaviour already in place for standalone functions. Cross-file throws propagation and the "Update docblock" code action produce correct results when the exception class is imported via a use statement.
• Missing diagnostics and import actions in files without a namespace. When a namespaced class (e.g. Carbon\Carbon) had already been parsed, using its short name (Carbon) in a file without a namespace declaration incorrectly resolved against the namespaced class. This suppressed both the "class not found" diagnostic and the "Import" code action. Bare-name lookups now only match classes that are themselves in the global namespace.
• Find-references false positives for global classes. Searching for references to a global-scope class (e.g. Helper with no namespace) could include references to unrelated namespaced classes with the same short name (e.g. App\Helper). Short-name fallback matching now only applies when the resolved name is unqualified.
• Fluent chains only flag the first broken link. In a chain where the first method does not exist, only that method is flagged instead of every subsequent call receiving its own warning.
• Null narrowing from !== null checks. Null-initialized variables guarded by $var !== null, !is_null(), or bare truthy checks now have null narrowed away inside the then-body and in subsequent && operands. Works in chained conditions, ternary expressions, and return statements.
• Variables assigned inside if/while conditions now resolve in the body. if ($admin = AdminUser::first()) and while ($row = nextRow()) register the assignment so the variable has a type inside the branch or loop body.
• Loop-body assignments not visible inside the same loop iteration. When a variable is initialized as null and reassigned later in a loop body, the assigned type is now visible at every point inside the loop. Combined with null narrowing, variables correctly resolve to the assigned class type.
• @var docblock annotations no longer leak across class and method boundaries. A @var annotation for a same-named variable in a different class no longer bleeds into the current scope.
• Inline @var cast no longer overrides the variable type on the RHS of the same assignment. /** @var array<string, mixed> */ $data = $data->toArray() no longer resolves the RHS $data using the cast type.
• Foreach over union types containing arrays now resolves the element type. A parameter typed User|array<User> iterated with foreach now correctly yields User as the loop variable type. Previously the element type extraction did not look inside union members, producing no completions.
• @param docblock overrides ignored when the native type hint resolves. When a parameter has both a native type hint and a more specific @param override, the docblock type now takes effect. Contributed by @calebdw in #55.
• Variable reassignment inside try/catch/finally blocks now tracked. Subsequent accesses within the same block resolve against the reassigned type instead of the original.
• Self-referential variable reassignments in nested loops no longer produce false "type could not be resolved" diagnostics. Recursive resolution that hits the depth limit no longer poisons the cache for later lookups.
• instanceof narrowing with unresolvable target class. When the target class cannot be loaded, the variable's type is treated as unknown instead of keeping the un-narrowed type, eliminating false positives for members on the narrowed subclass.
• stdClass and object types no longer produce false-positive diagnostics. Variables typed as object or stdClass now permit arbitrary property access. is_object() correctly narrows mixed to object and compound && conditions propagate the narrowing.
• Docblock type refinement no longer matches class names containing type keywords. A class named PointOfInterest would incorrectly be treated as an int refinement because the refinement check used substring matching. Refinement compatibility now uses structural type predicates.
• class-string<T> static method dispatch. Calling static methods on a class-string<Foo> variable now resolves return types correctly, including static substitution to the bound class.
• self/static/$this in cross-file method return types now resolve correctly. When a method on a cross-file class returns a type referencing self (e.g. @return HasMany<self, $this>), the owning class was looked up by short name through the consuming file's import table, which failed when the consuming file did not import that class. The owning class is now looked up by its fully-qualified name.
• in_array guard clause no longer wipes out variable type. When the haystack's element type matches the variable's type, the narrowing system no longer excludes the type entirely.
• Method chains through __call no longer lose the return type. When __call returns $this, static, or self, the chain type is preserved through dynamic method calls.
• Scope methods on Eloquent Builder no longer produce false-positive diagnostics. Bare Builder return types on scope methods are automatically wrapped as Builder<ConcreteModel> to preserve the chain.
• Scope methods missing from completion on relationship results. Scope methods from related models now appear in completions, not just hover.
• Closure and variable hover now preserves generic arguments. Closure parameters inferred from callable signatures, variables assigned from chained methods returning static/$this/self, and hovering on the $ sign of a variable at its assignment site all now show the correct generic type.
• Callable parameter inference preserves generic arguments from the receiver. A closure typed as fn(Builder $q) inside a Builder<Product> chain now infers $q as Builder<Product>, so model-specific scope methods resolve correctly.
• @see tags in floating docblocks now support go-to-definition. Docblock comments not directly attached to a class, function, or statement (e.g. inline /** @see SupervisorOptions::$balanceCooldown */ inside array literals or after expressions) are now parsed for symbol references. Previously these were silently ignored, particularly in files without a namespace.
• Nullable static return types on inherited methods. Methods returning ?static or static|null now correctly resolve to the calling subclass across files.
• Template binding with nested generics. Parameter types like Wrapper<Collection<T>, V> no longer break during template binding.
• Single generic argument on collections bound to the wrong template parameter. Collection<User> now binds to the value parameter instead of the key parameter when key-like template parameters precede value parameters.
• Nullable return types losing |null after template substitution. @return TValue|null now preserves |null through substitution, so calls like ::first() correctly show the nullable type.
• @mixin referencing a template parameter now resolves. A class with @template T and @mixin T now pulls in methods from the concrete type passed via generic arguments.
• @property and @method tags losing nullable types. Tags like @property int|null $foo no longer have |null stripped.
• Callable types inside unions displayed ambiguously. (Closure(int): string)|Foo is now parenthesized correctly in hover and completions.
• Hover and go-to-definition on attributes. Attributes on properties, class constants, parameters, and enum cases are now navigable.
• Function-level @template with generic wrapper parameters. Template substitution at call sites now correctly handles array, iterable, and list as wrapper names.
• Closure parameter inference from function-level @template bindings. Functions like array_any and array_all now infer concrete types for untyped closure arguments from the array parameter's element type.
• Property chain arguments in template substitution. Expressions like $this->items passed to templated functions now resolve their type for template binding.
• Variadic parameter element type lost in foreach. Iterating over a variadic parameter now resolves the loop variable to the element type.
• Anonymous class variables now resolve their type. $model = new class extends Foo { ... } followed by $model->method() now resolves through the anonymous class's inherited members.
• Namespaced functions imported via use function no longer flagged as unknown. Functions defined in one file and imported via use function in another now resolve correctly.
• parent::method() return type resolution in variable analysis. Calling parent::method() and assigning the result now correctly resolves the parent method's return type.
• Closure parameter inference inside switch cases and if conditions. Closure parameters that should be inferred from the enclosing callable context now resolve correctly when the closure appears inside a switch case or if-condition.
• Generic arguments propagated through transitive @extends chains. When a class extends a parent that itself extends a generic grandparent, generic arguments now flow through the full chain.
• Stack overflow when a foreach value variable shadows the iterator receiver. Patterns like foreach ($category->getBranch() as $category) no longer cause infinite recursion.
• PHPStan * wildcard in generic type arguments. Type strings like Relation<TRelatedModel, *, *> now parse correctly.
• Types with covariant or contravariant variance annotations in generic args now parse correctly. Annotations like BelongsTo<Category, covariant $this> no longer cause the entire type to become unresolvable.
• Diagnostics now work for vendor files open in the editor. Projects using --prefer-source or monorepo setups no longer have diagnostics suppressed in vendor files.
• PHPStan diagnostics no longer hidden by unrelated native diagnostics on the same line. Deduplication now only suppresses a full-line diagnostic when the precise diagnostic on the same line reports a related issue.
• Nullable boolean properties now use is prefix for getters. Properties typed ?bool or ?boolean now generate isFoo() instead of getFoo() when using the "Generate getter" code action.
• Aliased namespace imports used in attributes no longer flagged as unused. use Symfony\Component\Validator\Constraints as Assert; with #[Assert\Uuid(...)] no longer produces a false "Unused import" diagnostic.
• DB::select() return type. DB::select() and related methods now return array<int, stdClass> instead of bare array, and DB::selectOne() returns ?stdClass.
• Redis Connection method resolution. Redis commands on Illuminate\Redis\Connections\Connection now resolve through the phpredis stubs.
• Array shape tracking from keyed assignments inside conditional branches. Shape types built incrementally with variable keys inside loops with if/else branching are now preserved through foreach iteration.
• Deprecated class in implements renders with strikethrough. Deprecated classes referenced in implements clauses are correctly tagged.
• Interleaved array access and property chains no longer produce false positives. Expressions like $results[$i]->activities[$id]->extras where array subscript and property access alternate were incorrectly parsed, causing the intermediate property chain to be dropped. This led to "Property not found on class" false positives when the element type was resolved but the subsequent property lookup was skipped.
• FQN \assert() now narrows types. Writing \assert($var instanceof Foo) with a leading backslash was not recognized as an instanceof narrowing, causing false-positive "property not found" diagnostics after the assertion.
• Generic template substitution producing invalid types. When a template parameter was the base of a generic type (e.g. T<int> where T maps to Collection<string>), the substitution produced malformed types like Collection<string><int>. The replacement's base name is now used correctly, yielding Collection<int>.

0.6.0 - 2026-03-26

Added

• Semantic Tokens. Type-aware syntax highlighting that goes beyond what a TextMate grammar can achieve. Classes, interfaces, enums, traits, methods, properties, parameters, variables, functions, constants, and template parameters all get distinct token types. Modifiers convey declaration sites, static access, readonly, deprecated, and abstract status.
• PHPStan diagnostics. PHPStan errors appear inline as you edit. Auto-detects vendor/bin/phpstan or $PATH. Runs in the background without blocking native diagnostics. Configurable via [phpstan] in .phpantom.toml (command, memory-limit, timeout). "Ignore PHPStan error" and "Remove unnecessary @phpstan-ignore" code actions manage inline ignore comments.
• Formatting. Built-in PHP formatting (PER-CS 2.0 style). Formatting works out of the box without any external tools. Projects that depend on php-cs-fixer or PHP_CodeSniffer in their composer.json require-dev automatically use those tools instead (both can run in sequence). Per-tool command overrides and disable switches in [formatting] in .phpantom.toml.
• Inlay hints. Parameter name and by-reference indicators appear at call sites. Hints are suppressed when the argument already makes the parameter obvious: variable names matching the parameter, property accesses with a matching trailing identifier, string literals whose content matches, well-known single-parameter functions like count and strlen, and spread arguments. Named arguments never receive a redundant hint.
• PHPDoc block generation. Typing /** above any declaration generates a docblock skeleton. Tags are only emitted when the native type hint needs enrichment. Properties and constants always get @var. Class-likes with templated parents or interfaces get @extends/@implements tags. Uncaught exceptions get @throws with auto-import. Works both via completion and on-type formatting.
• Syntax error diagnostic. Parse errors from the Mago parser now appear as Error-severity diagnostics instantly as you type.
• Implementation error diagnostic. Concrete classes that fail to implement all required methods from their interfaces or abstract parents are now flagged with an Error-severity diagnostic on the class name. The existing "Implement missing methods" quick-fix appears inline alongside the error.
• Argument count diagnostic. Flags function and method calls that pass too few arguments. The "too many arguments" check is off by default (PHP silently ignores extra arguments) and can be enabled with extra-arguments = true in the [diagnostics] section of .phpantom.toml.
• Completion item documentation. Selecting a completion item in the popup now shows rich documentation including the full typed signature, description, deprecation notice, and parameter details. Previously only the class name was shown.
• Method commit characters. Typing ( while a method completion is highlighted auto-accepts it and begins the argument list.
• Document Symbols. The outline sidebar and breadcrumbs now show classes, interfaces, traits, enums, methods, properties, constants, and standalone functions with correct nesting, icons, visibility detail, and deprecation tags.
• Workspace Symbols. "Go to Symbol in Workspace" (Ctrl+T / Cmd+T) searches across all indexed files including vendor classes. Results include namespace context and deprecation markers, sorted by relevance.
• Type Hierarchy. "Show Type Hierarchy" on any class, interface, trait, or enum reveals its supertypes and subtypes with full up-and-down navigation through the inheritance tree, including cross-file resolution and transitive relationships.
• Code Lens. Clickable annotations above methods that override a parent class method or implement an interface method. Clicking navigates to the prototype declaration.
• Update docblock. Code action on a function or method whose existing docblock is out of sync with its signature. Adds missing @param tags, removes stale ones, reorders to match the signature, fixes contradicted types, and removes redundant @return void. Refinement types and unrelated tags are preserved. Only triggers on the signature or the preceding docblock, not inside the function body.
• Change visibility. Code action on any method, property, constant, or promoted constructor parameter offers to change its visibility (public, protected, private). Only triggers on the declaration signature, not inside the body.
• @throws code actions. Quick-fixes for adding missing and removing unnecessary @throws tags, triggered by PHPStan diagnostics. Adding inserts the tag and a use import when needed. Removing cleans up orphaned blank lines and deletes the entire docblock when it would be empty. The diagnostic disappears on the next keystroke without waiting for the next PHPStan run.
• File rename on class rename. Renaming a class whose file follows PSR-4 naming now also renames the file to match. The file is only renamed when it contains a single class-like declaration and the editor supports file rename operations.
• Folding Ranges. AST-aware code folding for class bodies, method/function bodies, closures, arrays, argument/parameter lists, control flow blocks, doc comments, and consecutive single-line comment groups.
• Selection Ranges. Smart select / expand selection returns AST-aware nested ranges from innermost to outermost.
• Document Links. require/include paths are now Ctrl+Clickable. Path resolution supports string literals, __DIR__ concatenation, dirname(__DIR__), dirname(__FILE__), and nested dirname with levels.
• Analyze command. phpantom_lsp analyze scans a Composer project and reports PHPantom's own diagnostics in a PHPStan-like table format. Useful for measuring type coverage across an entire codebase without opening files one by one. Accepts an optional path argument to limit the scan to a single file or directory. Output includes diagnostic identifiers and supports --severity filtering and --no-colour for CI.
• Null-coalesce (??) type refinement. When the left-hand side of ?? is provably non-nullable (e.g. new Foo(), clone $x, a literal), the right-hand side is recognized as dead code and the result resolves to the LHS type only. When the LHS is nullable (e.g. a ?Foo return type), null is stripped from the LHS and the result is the union of the non-null LHS with the RHS.
• @mixin generic substitution. When a class declares @mixin Foo<T>, the generic arguments are now preserved and substituted into the mixin's members, including through multi-level inheritance chains.
• PHPDoc @var completion. Inline @var above variable assignments sorts first and pre-fills the inferred type when available. Template parameters from @template enrich @param, @return, and @var type hints.
• @see and @link improvements. @see references in docblocks now work with go-to-definition (class, member, and function forms). Hover popups show all @link and @see URLs as clickable links. Deprecation diagnostics include @see targets when the @deprecated docblock references them.
• Progress indicators. Go to Implementation and Find References now show a progress indicator in the editor while scanning.
• Phar archive class resolution. Classes inside .phar archives (e.g. PHPStan's phpstan.phar) are now discovered and indexed automatically. No PHP runtime needed. Only uncompressed phars are supported (the format used by PHPStan and most other phar-distributed tools).
• PSR-0 autoload support. Packages that use the legacy PSR-0 autoloading standard are now discovered automatically.
• Global config. Settings from a global .phpantom.toml in the user's config directory (typically ~/.config/phpantom_lsp/.phpantom.toml) are now loaded as defaults. Project-level configs take precedence. Contributed by @calebdw in #39.
• Config schema. A JSON schema for .phpantom.toml is now bundled, enabling autocompletion and validation in editors that support TOML schemas. Contributed by @calebdw in #38.

Changed

• Pull diagnostics. Diagnostics are now delivered via the LSP 3.17 pull model when the editor supports it. The editor requests diagnostics only for visible files, and cross-file invalidation no longer recomputes every open tab. Clients without pull support fall back to the previous push model automatically.
• Hover type accuracy. Hover now resolves variable types through the same pipeline as completion, so all narrowing features (instanceof, assert, custom type guards, in_array) apply. When the cursor is inside a specific if/else branch, hover shows only the type visible in that branch. Complex expressions like null-coalesce chains, array shapes, empty arrays, and unresolved symbols all display correctly.
• Version-aware stub types. Built-in function signatures that changed across PHP versions (e.g. int|false in 7.x becoming int in 8.0) now show the correct type for your project's PHP version. This eliminates false-positive diagnostics and incorrect completions from stale type annotations.
• Completion labels. Method and function completion items now show only parameter names in the label (e.g. setName($name)) with the return type displayed inline (e.g. : User). Properties and constants show just the type hint. The previous Class: ClassName detail line has been removed; class context is available in the documentation panel when the item is highlighted.
• Completion sort order. Member completion items are now sorted by kind (constants, then properties, then methods) before alphabetical order within each group. Union-type completions apply the same kind-based ordering within both the intersection and branch-only tiers.
• Class name completion ranking. Completions now rank by match quality first (exact match, then starts-with, then substring), so typing Order puts Order above OrderLine above CheckOrderFlowJob regardless of where the class comes from. Within each match quality group, use-imported and same-namespace classes appear first, followed by everything else sorted by namespace affinity (classes from heavily-imported namespaces rank higher).
• Use-import completion. Same-namespace classes no longer appear in use statement completions (PHP auto-resolves them without an import). Classes that are already imported are filtered out. Namespace affinity still ranks the remaining candidates.
• Deprecation tags. Completion items use the modern tags: [DEPRECATED] field instead of the legacy deprecated boolean. Both convey the same strikethrough rendering in editors.
• Import class code action ordering. The "Import Class" code action now sorts candidates by namespace affinity (derived from existing imports) instead of alphabetically, so the most likely namespace appears first.
• Cross-file resolution. Completion, hover, and go-to-definition no longer fail when one reference uses a leading backslash and another does not.
• Embedded stubs track upstream master. The bundled phpstorm-stubs are now pulled from the master branch instead of the latest GitHub release, matching what PHPStan does. This brings in upstream fixes and new PHP version annotations weeks or months before a formal release.

Fixed

• CLI analyze performance. Single-file analysis is up to 5.8× faster. Full-project analysis of ~2 500 files is up to 10× faster.
• Diagnostic performance on large files. Unknown-member diagnostics on files with many member accesses are up to 7× faster.
• Position encoding. All LSP position conversions now correctly count UTF-16 code units, matching the LSP specification. Files containing emoji or supplementary Unicode characters no longer produce incorrect positions.
• Rename and find references for parameters. Renaming a parameter in a function, method, or closure now correctly updates all usages in the body and the @param tag in the docblock. Previously, parameters were scoped incorrectly because they sit physically before the opening { of the body, causing rename and find references to miss body usages when triggered from the parameter (and vice versa). Document highlight is also fixed.
• Rename updates imports. Renaming a class now updates use statement FQNs, preserves explicit aliases, and introduces an alias when the new name collides with an existing import.
• False-positive diagnostics for $this inside traits. Accessing host-class members via $this->, self::, static::, or parent:: inside a trait method no longer produces "not found" warnings, including chain expressions and accesses inside closures or arrow functions nested within trait methods.
• False-positive diagnostics for same-named variables in different methods. Diagnostic resolution is now scoped to the enclosing function/method/closure body, so two methods using a variable like $order resolve it independently.
• False positive on namespaced constants. Standalone namespaced constant references (e.g. \PHPStan\PHP_VERSION_ID) no longer produce a spurious "Class not found" diagnostic. Previously the symbol map classified them as class references instead of constant references.
• Diagnostic deduplication. Multiple diagnostics on the same span or line are no longer collapsed into one. If PHPStan reports five issues on a line, all five are shown. When PHPantom and PHPStan both flag the same issue, the more precise native diagnostic wins.
• Diagnostics. Enums that implement interfaces are now checked for missing methods. Scalar member access errors detect method-return chains where an intermediate call returns a scalar type. By-reference @param annotations no longer produce a false "unknown class" diagnostic.
• Removed PHP symbols in stubs. Functions, methods, and classes annotated with @removed X.Y in phpstorm-stubs are now filtered out when the target PHP version is at or above the removal version. Previously symbols like mysql_tablename (removed in PHP 7.0) and each (removed in PHP 8.0) appeared in completions and resolved without warnings.
• Hover on union member access. Hovering over a method, property, or constant on a union type (e.g. $ambiguous->turnOff() where $ambiguous is Lamp|Faucet) now shows hover information from all branches that declare the member, separated by a horizontal rule. Previously only the first matching branch was shown. When both branches inherit the member from the same declaring class, the hover is deduplicated to a single entry.
• Hover on inherited members. Hovering over an inherited method, property, or constant now shows the declaring class in the code block (e.g. class Model { public static function find(...) }) instead of the class it was accessed on. Previously User::find() would incorrectly show class User even though find() is declared on Model.
• Constant type inference. Variables assigned from global constants ($a = MY_CONST) or class constants without type hints ($b = Config::TIMEOUT) now resolve to the type implied by the constant's initializer value. Integer, float, string, bool, null, and array literals are all recognised. Typed class constants (public const string NAME = '...') continue to use their declared type hint.
• Variable type after reassignment. When a method parameter is reassigned mid-body (e.g. $file = $result->getFile()), subsequent member accesses now resolve against the new type instead of the original parameter type.
• Variable assignments inside foreach loops. Variables conditionally reassigned inside a foreach body are now visible after the loop.
• Variable-to-variable type propagation. Assignments like $found = $pen now resolve $found to the type of $pen. This also eliminates false-positive diagnostics when the initial assignment was $found = null and a later reassignment provided the real type.
• Variable type inside self-referencing assignment RHS. In $request = new Foo(arg: $request->uuid), the $request reference inside the constructor arguments now correctly resolves to the original type instead of the type being assigned.
• Variable resolution inside anonymous classes. Variables inside anonymous class methods (e.g. closure parameters in return new class extends Migration { ... }) now resolve correctly. Previously, anonymous class bodies were invisible to the variable resolution pipeline because they appear as expressions inside statements rather than top-level class declarations.
• Closure and arrow function variable scope. Variable name completion now correctly respects PHP scoping rules for anonymous functions and arrow functions. Parameters and use-captured variables are visible inside closures. Arrow function parameters are visible inside the arrow body while the enclosing scope's variables remain accessible.
• Function return type resolution across files. Standalone functions that declare return types using short names from their own use imports now resolve correctly in consuming files. Function parameter types and @throws types are also resolved.
• Native type override compatibility. A docblock type only overrides a native type hint when it is a compatible refinement (e.g. class-string<Foo> can refine string, but array<int> no longer incorrectly overrides string).
• PHPStan pseudo-type recognition. Types like non-positive-int, non-negative-int, non-zero-int, lowercase-string, truthy-string, callable-object, and many other PHPStan pseudo-types are now recognized across the entire pipeline.
• Nullable and generic types in class lookup. Variables typed as ?ClassName or Collection<Item> now resolve correctly across all code paths.
• Generic substitution through transitive interface chains. When a class implements an interface that itself extends another generic interface, template parameters are now substituted at each level instead of propagating raw template parameter names.
• Generic shape substitution. Template parameters inside array shapes (array{data: T}) and object shapes (object{name: T}) are now correctly substituted when inherited through @extends.
• Type narrowing with same-named classes from different namespaces. instanceof narrowing now correctly distinguishes classes that share a short name but live in different namespaces (e.g. Contracts\Provider vs Concrete\Provider).
• Guard clause narrowing across instanceof branches. After if ($x instanceof Y) { return; }, subsequent instanceof checks on the same variable no longer incorrectly resolve to Y.
• instanceof self/static/parent narrowing. Type narrowing with instanceof self, instanceof static, and instanceof parent now works correctly in all contexts (assert, if-blocks, guard clauses, compound conditions).
• Type narrowing inside return statements. instanceof checks in && chains and ternary conditions now narrow the variable type when the expression is the operand of a return statement.
• Inline array access on method returns. Expressions like $c->items()[0]->getLabel() now resolve the element type correctly for both completion and diagnostics.
• Array shape bracket access. Variables assigned from string-key bracket access on array shapes ($name = $data['name']) now resolve to the correct value type. Chained access ($first = $result['items'][0]) walks through shape keys and generic element types in sequence.
• Ternary and null-coalesce member access. Accessing a member on a ternary or null-coalesce expression (e.g. ($a ?: $b)->property, ($x ?? $y)->method()) now resolves correctly for hover, go-to-definition, and diagnostics.
• Null-safe method chain resolution. Null-safe method calls ($obj?->method()) now resolve the return type correctly for variable type inference, including cross-file chains.
• Clone expressions. (clone $var)-> now resolves to the same type as $var, providing correct completion, hover, and diagnostics.
• self::/static::/parent:: in member access chains. Expressions like self::Active->value inside an enum method now resolve correctly. Previously, self, static, and parent were only recognized as bare subjects, not when followed by ::MemberName in a chain.
• Inherited methods missing through deep stub chains. Methods are now found on classes that inherit through multi-level chains where intermediate classes live in stubs.
• Interface constants through multi-extends chains. Constants defined on parent interfaces are now found when an interface extends multiple other interfaces.
• Double parentheses when completing calls. Completing a function, constructor, or static method name when parentheses already follow the cursor (e.g. array_m|(), new Gadge|(), throw new Excepti|()) no longer inserts a second pair of parentheses. Previously only -> and :: method calls were handled.
• Namespace alias completion. Typing a class name through a namespace alias (e.g. OA\Re with use OpenApi\Attributes as OA) now correctly suggests classes under the aliased namespace.
• Catch clause completion. Throwable interfaces and abstract exception classes now appear in catch clause completions.
• Type-hint and PHPDoc completion. Traits are now excluded from completions in parameter types, return types, property types, and PHPDoc type tags. @throws continues to use Throwable-filtered completion.
• Trait alias go-to-definition. Clicking a trait alias (e.g. $this->__foo() from use Foo { foo as __foo; }) now jumps to the trait method instead of the class's own same-named method.
• Self-referential array key assignments no longer crash. Patterns like $numbers['price'] = $numbers['price']->add(...) no longer cause a stack overflow during hover or completion.
• Eloquent morphedByMany relationships. The inverse side of polymorphic many-to-many relationships is now recognised. Virtual properties and _count properties are synthesized for models using this relationship type.
• Virtual property merging. Native type hints are now considered when determining virtual property specificity, preventing properties with native PHP type declarations from being incorrectly overridden by less specific virtual properties.

0.5.0 - 2026-03-12

Added

• Diagnostics. Unknown classes, unknown members, and unknown functions are flagged with appropriate severity. An opt-in unresolved member access diagnostic is available via .phpantom.toml.
• Find References. Locate every usage of a symbol across the project. Supports classes, methods, properties, constants, functions, and variables. Variable references are scoped to the enclosing function or closure. Member references are scoped to the class hierarchy, so unrelated classes sharing a method name are excluded.
• Rename. Rename variables, classes, methods, properties, functions, and constants across the workspace. Variable renames are scoped to their enclosing function or closure.
• Deprecation support. @deprecated tags and #[Deprecated] attributes surface in hover, completion strikethrough, and diagnostics. A quick-fix code action rewrites deprecated calls when a replacement template is available.
• Document highlighting. Placing the cursor on a symbol highlights all occurrences in the current file. Variables are scoped to their enclosing function or closure with write vs. read distinction.
• Implement missing methods. Code action that generates method stubs when a class is missing required interface or abstract method implementations.
• Project configuration. .phpantom.toml for per-project settings: PHP version override, diagnostic toggles, and indexing strategy. Run phpantom --init to generate a default config.
• Reverse go-to-implementation. Go-to-implementation on a concrete method jumps to the interface or abstract class that declares the prototype, and vice versa.
• Go to Type Definition. Jump from a variable, property, method call, or function call to the class declaration of its resolved type. Union types produce multiple locations.
• Self-generated classmap. PHPantom works without composer dump-autoload -o. Missing or incomplete classmaps are supplemented by scanning autoload directories. Non-Composer projects are supported by scanning all PHP files.
• Monorepo support. Discovers subdirectories that are independent Composer projects and processes each through the full pipeline.
• @implements generic resolution. @implements Interface<ConcreteType> substitutes template parameters on the interface's methods and properties. Foreach iteration on generic iterable interfaces resolves value and key types.
• Interface template inheritance. Implementing classes inherit @template parameters, bindings, conditional return types, and type assertions from their interfaces.
• Function-level @template with generic return types. Functions that use @template parameters inside generic return types now resolve concrete types from call-site arguments.
• Generic @phpstan-assert with class-string<T>. Assertion methods that accept a class-string<T> parameter resolve the narrowed type from the call-site argument.
• Property-level narrowing. if ($this->prop instanceof Foo) narrows $this->prop in then/else bodies and after guard clauses.
• Inline && short-circuit narrowing. The right-hand side of && now sees the narrowed type from the left-hand side.
• Compound negated guard clause narrowing. if (!$x instanceof A && !$x instanceof B) { return; } narrows $x to A|B in the surviving code.
• Closure variable scope isolation. Variables outside a closure are no longer offered as completions unless captured via use().
• Pipe operator (PHP 8.5). $input |> trim(...) |> createDate(...) resolves through the chain.
• AST-based array type inference. Array shape keys, element access, spread elements, and push-style assignments all resolve through an AST walker.
• new $classStringVar and $classStringVar::method(). Class-string variables resolve for new and static member access.
• Invoked closure and arrow function return types. (fn(): Foo => ...)() and (function(): Bar { ... })() resolve to their return type.
• Docblock navigation. Go-to-definition and hover work on class names inside callable types, array/object shape value types, and object shape properties.
• GTD from parameter and property variables. Clicking a parameter or property at its definition site jumps to the type hint class.
• PHP version-aware stubs. Detects the target PHP version from composer.json and filters built-in stub signatures accordingly.
• @param-closure-this. $this inside a closure resolves to the type declared by @param-closure-this on the receiving parameter.
• Non-Composer function and constant discovery. Cross-file function completion, go-to-definition, and constant resolution for projects without composer.json.
• Indexing progress indicator. The editor shows a progress bar during workspace initialization, including per-subproject progress in monorepos.
• Pass-by-reference parameter type inference. After calling a function with a typed &$var parameter, the variable acquires that type.
• iterator_to_array() element type. Resolves the element type from the iterator's generic annotation.
• Enum case properties. $case->name and $case->value resolve on enum case variables.
• Inline @var on promoted constructor properties. Overrides the native type hint, matching existing @param support.
• --version and --help CLI flags. Contributed by @calebdw in #7.

Changed

• Resolution engine rewritten on AST. Variable type inference, call return types, and go-to-definition all run through the AST walker for better accuracy.
• Hover redesigned. Short names with namespace line, actual default values, @link URLs, precise token highlighting, constructor signatures on new, @template details, enum case listing, trait member listing, origin indicators, and deprecated explanations.
• Signature help enriched. Compact parameter list with native types, per-parameter @param descriptions, default values, and attribute parenthesis support.
• Faster resolution and lower memory usage.
• Parallel workspace indexing. File parsing, PSR-4 scanning, and vendor scanning run across all CPU cores. .gitignore rules are respected.
• Two-phase diagnostic publishing. Cheap diagnostics (unused imports, deprecation) publish immediately; expensive diagnostics (unknown classes/members/functions) arrive in a second pass.
• Merged classmap + self-scan pipeline. Composer classmaps and self-scanning work together instead of being mutually exclusive. Stale classmaps are supplemented automatically.
• Automatic stub fetching. The build script downloads phpstorm-stubs automatically when missing. Composer is no longer needed to build PHPantom. Contributed by @calebdw in #16.
• Feature comparison table corrected. Phactor capabilities updated in the README. Contributed by @dantleech in #10.
