Phalcon's event system allows us to execute custom actions before or after certain events occur in our application. Here are the steps to use the event system in Phalcon:

  1. Register an event manager in your bootstrap file:
1
$eventsManager = new PhalconEventsManager();


  1. Create an event listener class and define your custom logic in its callback method:
1
2
3
4
5
6
7
class SomeListener
{
    public function logSomething(PhalconEventsEvent $event, PhalconMvcDispatcher $dispatcher, $data)
    {
        // your custom logic here
    }
}


  1. Register the event listener with the event manager:
1
$eventsManager->attach('some:event', new SomeListener());


  1. Trigger the event in your code where you want your listener to be called:
1
$dispatcher->getEventsManager()->fire('some:event', $dispatcher, $data);


Note: $dispatcher is an instance of PhalconMvcDispatcher that we can use to trigger events in our controller or view.


That's it! The listener's logSomething() method will be executed when the some:event event is triggered. You can add as many listeners as you need for different events in your application.
