Mediator

Mediator in PHP

Mediator is a behavioral design pattern that reduces coupling between components of a program by making them communicate indirectly, through a special mediator object.

The Mediator makes it easy to modify, extend and reuse individual components because they’re no longer dependent on the dozens of other classes.

Complexity:

Popularity:

Usage examples: The pure implementation of the Mediator pattern isn’t as common in PHP, as it’s in other languages, especially GUI-targeted like Java or C#. A PHP application may indeed contain dozens of components, but they rarely communicate directly within a single session.

However, there are still uses for the Mediator pattern like the event dispatchers of many PHP frameworks or some implementations of MVC controllers.
