To Do

• Quiz
  • Basic class
  • Class with chaining
  • Class that accepts same type of class
  • Class that accepts another class
  • Interface
  • Inheritance
  • Three level interface interaction (e.g. Library, Shelf, Book)
• Interfaces challenges
  • Recreate Bike challenge using classes for everything
• Some more basic static challenges
• More on static
  • Explain better
  • Include example of using People instead - better type safety but harder for other people to use
• OOP: Keep objects as objects for as long as possible
• Demonstrate creating collection in constructor
• When to use a constructor
  • If excepting arguments
  • If setting something up (e.g. collect)
• Pre-week reading, to get through basic-PHP stuff and regex in one day?
• Rewrite Law of Demeter
• Explain when to use interfaces

  When you write a class that takes an object as an argument to a method

• More regex challenges
  • preg_split
  • preg_replace
  • Tricksy: back references
• Cover capture groups in preg_replace
• Typed properties (PHP 7.4+)
• Guide to writing classes
  • Does it accept arguments: __construct
  • Does it need default values?
  • What methods does it need?
• Inheritance challenge with two parts: a) use inheritance b) use composition
• Mention use partial namespace with use - e.g. App\Cutlery so you can then do new Cutlerty\Spoon()
• lastName method used in static section of notes, but not actually in Person class

Doing

Done

• Type hinting arrays, scalars
• Git repos to get setup for the challenges
• Cover encapsulation earlier - with objects?
• Cover flags in regex
• Mention brackets for grouping specifically in regex
• Interfaces before Inheritance
  • Always use interfaces for polymorphism
  • Only use inheritance for definitely shared behaviour
• Talk about return type declarations
  • Clear up type hint vs type declaration
• Mention single responsibility principle in OOP notes
• Is static necessary for caching in recipe static question? Just stored as a property
• Architecture before OOP
• Namespace challenges need clearer setup instructions to make sure they're doing it properly
• Move static to post-encapsulation?
• Update autoloading challenges so no chaining or objects using other objects
  • Move spares into OOP/static
  • Add namespaces to OOP/static challenges
• OOP Challenges
  • Add template repo
  • Should use autoloading
• Separate static challengs and point to right place
  • Add static challenge to use a collection class (People) instead of static
