Stand-alone library of Symfony EventDispatcher that can be used in any PHP framework or just pure PHP probject.

If you're looking simple one please visit: https://github.com/shinbonlin/PHP-EventDispatcher

What's the different than original?

Nothing is changed except:

1. Remove namespace and use
2. Combine mutli files into one file.
3. ContainerAwareEventDispatcher.php and /DependencyInjection/RegisterListenersPass.php are not included.

Just made it can be easy used in just 10 seconds without installing by Composer.

Original: https://github.com/symfony/EventDispatcher

1. Copy EventDispatcher.php and put it in application/libraries folder.
2. Create MY_Controller.php in core folder.
3. Edit MY_Controller.php

class MY_Controller extends CI_Controller
{


    public $event;

	public function __construct() {
        parent::__construct();

		$this->load->library('EventDispatcher');
		$this->event = new EventDispatcher();
    }
}

Register an Event

    $this->event->addListener('event_name', function () {
        echo 'Hello, World!';
    });

Run an Event

    $this->event->dispatch('event_name');

Result

Hello, World!

Example Code

$event = new EventDispatcher();

$event->addListener('event_name', function () {
    echo 'Hello, World!';
});

$event->dispatch('event_name');

Hope this helps.
