createEventEmitter() публичный Метод

Set as second argument a emitter instance, otherwise the factory creates a new one. Event array could have a name-handler-pair, a listener provider as instance of \League\Event\ListenerProviderInterface or a argument array with name, handler and priority Configure event array as follows: $events = [ name-handler-pair 'eventName' => function()}, listener provider as instance of \League\Event\ListenerProviderInterface new \Acme\MyListenerProvider argument array name, handler, prio ['name', function()}, 10] alternating argument array name => [handler, prio] 'eventName' => [function()}, 10] ];

public createEventEmitter ( League\Event\ListenerProviderInterface \| array $events = [], League\Event\EmitterInterface $emitter = null ) : League\Event\Emitter
$events	League\Event\ListenerProviderInterface \| array
$emitter	League\Event\EmitterInterface
Результат	League\Event\Emitter
