DevShed:
Introducing Mediator Classes in PHP 5
March 13, 2007 @ 11:22:00

DevShed starts off another design patterns series with this new article introducing the Mediator class pattern - a method to keep things up to date and synchronized in your PHP application.

Well, in this case, the synchronization between a group of PHP classes can be made by implementing a useful pattern widely known as "mediator." In short, when the mediator pattern is applied, there's a single class that implements the logic required to keep all the other classes completely synchronized with each other. This means that not only will all the modifications introduced by one class be reflected in the others, but that those changes will be performed via the interface of the mediator class.

They Apply this pattern with their traditional example of working with files - this time the class will handle the communication (and syncing) between two file handling objects. They add a file handling class on to the back end and apply them both in an example that lets you manipulate the data inside both files at the same time.
