Events

• Usage

The event class lets you register event listeners and trigger them.

Usage

The phpregister method lets you register an event listener that will run when triggered.

Event::register('foobar', function()
{
	return 'foobar event 1';
});

// You can register multiple handlers for the same event.
// They will be run in the order they were registered.

Event::register('foobar', function()
{
	return 'foobar event 2';
});

The phpregistered method will return TRUE if an event listener has been registered and FALSE if not.

$registered = Event::registered('foobar'); // True

The phpclear method will clear all event listeners registered for an event.

Event::clear('foobar');

The phpoverride method will clear all previously registered handlers for an event before registering a new handler.

Event::override('foobar', function()
{
	return 'foobar event 1';
});

The phptrigger method run all handlers for the registered event and return an array containing all the return values.

$values = Event::trigger('foobar');

// You can also pass an array of values

$values = Event::trigger('foobar', array(1, 2, 3));

The phpfirst method run all handlers for the registered event and return the result of the first one.

$value = Event::first('foobar');

// You can also pass an array of values

$values = Event::first('foobar', array(1, 2, 3));
