EventDispatcher Component

The Symfony EventDispatcher component implements the Mediator pattern in a simple and effective way to make your projects truly extensible.

```php use Symfony; use Symfony;

$dispatcher = new EventDispatcher();

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

$dispatcher->dispatch('event_name'); ```
