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 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.

Please feel free to fork and add your own examples!

Changes I've made :

• Adding a config and autoloader for PHPUnit
• Fixing PSR-0 for namespace and one class per file (for tested patterns)
• Moving the original Factory Method in its right place : Static Factory (+ Tests)
• Adding the Simple Factory pattern (+ Tests)
• Adding a real Factory Method Design Pattern "by the book" (+ Tests)
• Rewriting the Abstract Factory which was not a abstract factory by the GoF definition (+ Tests)
• Fixing Composite Pattern which was not a Composite pattern (+ Tests)
• Fixing Decorator Pattern which was only a Wrapper pattern (+ Tests)
• Comments on why iterator pattern example is not relevant
• Adding a new Iterator example without external influence of other pattern (+ extended Tests)
• Adding a more visual example for Facade pattern (+ Tests)
• Fixing the Command pattern by adding missing mandatory classes (+ Tests)
• Fixing the Adapter Pattern because it was buggy and incomplete (+ Tests)
• Adding Template Method Pattern (+ Tests)
• Adding Builder Pattern (+ Tests)
• Adding Mediator Pattern (+ Tests)
• Adding a full example of Chain of Responsibilities (+Tests)
• PSR-0 for FluentInterface & Tests
• Null Object Pattern (+ Tests)
