design patterns in PHP

This is a collection of known design patterns and some sample code how to implement them in PHP. Every pattern has a small list of examples (most of them from Zend Framework, Symfony2 or Doctrine2 as I'm most familiar with this software).

I think the problem with patterns is that often people do know them but don't know when to apply which.

The patterns can be structured in roughly three different categories:

Creational

• AbstractFactory
• Builder
• SimpleFactory
• FactoryMethod
• StaticFactory
• Prototype
• Singleton (is considered an anti-pattern! ⛔)
• Multiton (is considered an anti-pattern! ⛔)

Structural

• Adapter
• Composite
• Decorator
• Facade
• Proxy
• Registry
• FluentInterface
• DataMapper
• DependencyInjection

Behavioral

• ChainOfResponsibilities
• Command
• Iterator
• Mediator
• NullObject
• Observer
• StatusPattern
• Strategy
• TemplateMethod
• Visitor
