PHP Event Dispatcher

This package can register events and call registered listeners.

It can register an event listener by associating a name to a callback function that will be invoked when an event with that name happens.

Event listeners may be registered to handle a group of events defined by a event name pattern.

The event name matching may be defined also by an object that determines if a given event should be handled by the subscribed event handler.

Events are be dispatched by calling the registered event listeners.

Registered event listeners may have an associated priority number so they can be called by the order defined by their priority.

Event listeners callback functions may take parameters that define the context of the event.
