Usage

Delegates

use Scabbia\Events\Delegate;

$delegate = new Delegate();

$delegate->subscribe(function (...$parameters) {
    echo 'first subscriber:';
    var_dump($parameters);
});

$delegate->subscribe(function (...$parameters) {
    echo 'second subscriber:';
    echo count($parameters);
});

$delegate->invoke('a', 'b', 'c');

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');

Delegates with breaking

use Scabbia\Events\Delegate;

$delegate = new Delegate();

$delegate->subscribe(function (...$parameters) {
    echo 'first subscriber:';
    var_dump($parameters);

    // breaks the execution
    return false;
});

$delegate->subscribe(function (...$parameters) {
    echo 'second subscriber, but not going to be executed:';
    echo count($parameters);
});

$delegate->invoke('a', 'b', 'c');

Events

use Scabbia\Events\Events;

$eventsManager = new Events();

$eventsManager->on('click', function (...$parameters) {
    echo "clicked on x={$parameters[0]} and y={$parameters[1]}!";
});

$eventsManager->on('double_click', function (...$parameters) {
    echo 'double clicked!';
