Creates, Manages, and Fires events during your project runtime

composer require jemer/event-dispatcher dev-main

Adding Events

Events are added on creation.

$manger = new Manager([
    'load',
    'unload',
    'before_render',
    'after_render'
]);

This will add load unlodad before_render after_render events that you can hook into. Note you can add your own events and call them whatever you want.

Handling Events

Events can either be handled by a Closure, or a Class.

Closure

$manger->Register('load', function()
{
    echo "this will run when the Load event get triggered";
});

Class

<?php 

namespace Jemer\Test;

use Jemer\EventDispatcher\ObserverBase;

class TestObserver extends ObserverBase
{
    public function Load() : void
    {
        // use this to load in any resources this observer will need
        // Load() will be called immediately before Run()
        echo "Load()";
    }

    public function Run() : void
    {
        // run your code here
        echo "Run()";
    }
}

?>

When using a class to handle your events you must use the Load() and Run(). Use Load() to load in any resources you will need, and use Run() to handle your event. Load is called immediately before Run . When using a Closure there is no Load().

Firing an Event

In your project when you need to fire off an event such as load simply

$manger->FireEvent('load');

This will fire off the load event.
