You need an Event and an EventHandler.
Let's say we have an event class stored in app/eventing/event/UserWasRegistered.php.
namespace App\Eventing\Event;
class UserWasRegistered extends \TomWright\Eventing\Event\Event
{
protected $userId;
public function setUserId($userId)
{
$this->userId = $userId;
}
public function getUserId()
{
return $this->userId;
}
}Let's also assume we have an event handler class stored in app/eventing/handler/UserWasRegisteredHandler.php.
namespace App\Eventing\Handler;
class UserWasRegisteredHandler implements \TomWright\Eventing\Listener\ListenerInterface
{
public function handle(\TomWright\Eventing\Event\EventInterface $event)
{
echo "User #{$event->getUserId()} has been registered.";
}
}Now we need to add an Event Handler/Listener namespace so as the EventBus knows where to look for the handlers.
$bus = \TomWright\Eventing\EventBus::getInstance();
$bus->addListenerNamespace('\\App\\Eventing\\Handler');Now whenever we register a new user, all we have to do is the following:
$bus = \TomWright\Eventing\EventBus::getInstance();
$event = new \App\Eventing\Event\UserWasRegistered();
$event->setUserId(123);
$bus->dispatch($event);
