EventDispatcher Component

EventDispatcher implements a lightweight version of the Observer design pattern.

use Symfony\Component\EventDispatcher\EventDispatcher;
use Symfony\Component\EventDispatcher\Event;

$dispatcher = new EventDispatcher();

$dispatcher->addListener('event_name', function (Event $event) {
    // ...
});

$dispatcher->dispatch('event_name');

Resources

You can run the unit tests with the following command:

phpunit

If you also want to run the unit tests that depend on other Symfony Components, install dev dependencies before running PHPUnit:

php composer.phar install --dev
