Answer / surbhi
Events and Listeners serve a great way to decouple a web application, since one event can have multiple listeners which are independent of each other.
The events folder created by the artisan command includes the following two files
1. : event.php
2. :SomeEvent.php.
Event.php
<?php
namespace AppEvents;
abstract class Event{
//
}
As mentioned above, event.php includes the basic definition of class Event and calls for namespace AppEvents. Please note that the user defined or custom events are created in this file.
SomeEvent.php
For example, if we need to initialize order variable in the constructor for registering an event, we can do it in the following way -
public function __construct(Order $order)
{
$this->order = $order;
}
