DevShed:
Object Interaction and Mediator Classes in PHP 5
March 21, 2007 @ 11:16:00

DevShed wraps up yet another in their design pattern series of articles today with this new tutorial - the final part in their look at using Mediator classes in PHP5.

At this stage I believe that implementing the mediator pattern with PHP 5 should be a pretty painless process to you, but if the examples that I showed you in the first article weren't enough to help you completely grasp this pattern, over the course of this last tutorial I'm going to expand the original mediator class that you learned previously. The expansion will make it capable of maintaining three classes in perfect synchronization.

They start off with the base Mediator class they developed in previous parts of the series and expand it out some more with the functionality needed to keep three (not just two) objects synchronized. To help out, they build some more file handling classes, ones that work with the three different types - numeric, alpha, and alphanumeric content.
