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.

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

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

You can optionally build and browse the documentation using Docker for Mac, Windows or Linux.

Just run:

$ docker-compose up --build

Go to http://localhost:8080/README.html to read the generated documentation.

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