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.

Installation

You should look at and run the tests to see what happens in the example. To do this, you should install dependencies with Composer first:

$ composer install

Read more about how to install and use Composer on your local machine here.

To run the tests use phpunit:

$ ./vendor/bin/phpunit

using Docker (optional)

You can optionally run tests using Docker for Mac or Windows or native one for Linux. Just run:

$ docker-compose up

To only install the dependencies, use docker-compose like this:

$ docker-compose run composer install

Patterns

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

Creational

Structural

Behavioral
