DesignPatternsPHP

Read the Docs of DesignPatternsPHP or Download as PDF/Epub

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:

[optional] Using a Virtual Machine (VM)

If you wish to use a ready made VM environment, you can easily create one with Vagrant and Ansible.

$ vagrant up

Then vagrant ssh and cd /vagrant

More information on vagrant

Install dependencies

$ composer install

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

Running test suite

$ ./vendor/bin/phpunit

Patterns

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

FactoryMethod 📓
Multiton (is considered an anti-pattern! ⛔)
Pool 📓

Contribute

If you encounter any bugs or missing translations, please feel free to fork 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 ..
