The README.md

Dhii - Event Interface

, _(*1)

Details

The PSR-14 standard provides interfaces used for dispatching events. But what of events themselves? How can a consumer of the dispatcher (i.e. the emitter) interoperate with the handler, if they have no agreement on what an event may look like? This package aims to provide interfaces that could facilitate the interoperability of events that are identified by event name., _(*2)

Usage

Basic Features

In essence, an event is but a map of parameters associated with a name., _(*3)

make('my_event', ['key' => 'value']);
echo $event->getName(); // 'my_event'
echo $event->getParam('key'); //  'value'

$params = $event->getParams();
var_dump($params); // ['key' => 'value']

$params['hello'] = 'world';
$event->setParams($params);
echo $event->getParam('hello'); // 'world'
?>

With PSR-14

Evemts cam be dispatched using a standards-compliant event dispatcher. This example requires the already included [dhii/event-dispatcher-interface][] package., _(*4)

addListener('my_event', function (EventInterface $event) {
    $params = $event->getParams();
    $params['key'] = 'other_value';
    $event->setParams($params);
    $event->stopPropagation();
}, 1);

// Second listener is never run, therefore the value does not change again
$listenerMap->addListener('my_event', function (EventInterface $event) {
    $params = $event->getParams();
    $params['key'] = 'yet another value';
    $event->setParams($params);
}, 2);

$event = $factory->make('my_event', ['key' => 'value']);
$dispatcher->dispatch($event);
echo $event->getParam('key'); // 'other_value'
?>
