Release Notes

PHPCSStandards/PHP_CodeSniffer (squizlabs/php_codesniffer)

v4.0.1: - 2025-11-10

Compare Source

This release includes all improvements and bugfixes from PHP_CodeSniffer 3.13.5.

Added

• Runtime support for PHP 8.5. All known PHP 8.5 deprecation notices have been fixed.
  • Syntax support for new PHP 8.5 features will follow in a future release.
  • If you find any PHP 8.5 deprecation notices which were missed, please report them.

Changed

• The Squiz.ControlStructures.SwitchDeclaration sniff will now flag a PHP close tag as a "wrong opener" and will auto-fix this by inserting a colon. #​1316
• Various housekeeping, including improvements to the tests and documentation.

Fixed

• 4.x regression #​1277: bring back whitespace tolerance in phpcs:ignore comma-separated rule reference lists.
  • Note: this bug did not affect phpcs:disable/phpcs:enable ignore annotations.
• Fixed bug #​968: Generic.WhiteSpace.ScopeIndent was reporting false positives - and making incorrect fixes - for lines following a line containing an arrow function.
  • Thanks to Soichi Sato for the patch.
• Fixed bug #​1216: Tokenizer/PHP: added more defensive coding to prevent PHP 8.5 "Using null as an array offset" deprecation notices.
  • Thanks to Andrew Lyons for the patch.
• Fixed bug #​1279: Tokenizer/PHP: on PHP < 8.0, an unclosed attribute (parse error) could end up removing some tokens from the token stream.
  • This could lead to false positives and false negative from sniffs, but could also lead to incorrect fixes being made mangling the file under scan.
• Fixed bug #​1315: Squiz.ControlStructures.SwitchDeclaration: a number of the fixers would get into fixer conflicts with each other if the code under scan contained multiple statements on a line within a switch.
  • The sniff will now forbid - and auto-fix - multiple statements on one line for case/default and "case breaking" statements.
• Fixed bug #​1316: Tokenizer/PHP: a PHP close tag after a switch case condition or after a default keyword, was not regarded as a "scope_opener" for the case/default body.
• Fixed bug #​1316: PSR2.ControlStructures.SwitchDeclaration: the WrongOpener error is now also auto-fixable if the wrong opener is a PHP close tag.
• Fixed bug #​1316: Squiz.PHP.NonExecutableCode would throw false positives when code within a switch control structure would move in and out of PHP.

⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: composer.lock

Command failed: composer update squizlabs/php_codesniffer:4.0.1 --with-dependencies --ignore-platform-req='ext-*' --ignore-platform-req='lib-*' --no-ansi --no-interaction --no-scripts --no-autoloader --no-plugins --minimal-changes

Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires squizlabs/php_codesniffer ^4.0, found squizlabs/php_codesniffer[4.0.0, 4.0.1] but these were not loaded, likely because it conflicts with another require.
  Problem 2
    - laminas/laminas-coding-standard is locked to version 3.1.0 and an update of this package was not requested.
    - laminas/laminas-coding-standard 3.1.0 requires squizlabs/php_codesniffer ^3.10 -> found squizlabs/php_codesniffer[3.10.0, ..., 3.13.5] but it conflicts with your root composer.json require (^4.0).

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
