DesignPatternsPHP

Build Status

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.

Patterns

The patterns can be structured in roughly three different categories. Please click on the πŸ““ for a full explanation of the pattern on Wikipedia.

Creational

Structural

Behavioral

Contribute

Please feel free to fork and extend existing or add your own examples and send a pull request with your changes! To establish a consistent code quality, please check your code using PHP_CodeSniffer against PSR2 standard using ./vendor/bin/phpcs -p --standard=PSR2 --ignore=vendor ..
