Delegates with priorities
use Scabbia\Events\Delegate; $delegate = new Delegate(); // a subscription with priority = 300 $delegate->subscribe(function (...$parameters) { echo 'first subscriber:'; var_dump($parameters); }, null, 300); // a subscription with priority = 1 (will be executed first) $delegate->subscribe(function (...$parameters) { echo 'second subscriber, but more important:'; echo count($parameters); }, null, 1); $delegate->invoke('a', 'b', 'c');
