The `Laminas\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.

The Laminas Project is a PHP framework for developing web applications and services.
