zend-eventmanager

The Zend\EventManager is a component designed for the following use cases:

• Implementing simple subject/observer patterns.
• Implementing Aspect-Oriented designs.
• Implementing event-driven architectures.

The basic architecture allows you to attach and detach listeners to named events, both on a per-instance basis as well as via shared collections; trigger events; and interrupt execution of listeners.
