DevShed has posted part two in the series they've worked up covering overloading classes inside of a PHP4 environment. In this edition (two of three) they focus on method call overloading, a step up from the previous property overloading.

This is part two of the series "Overloading classes in PHP." In three tutorials, this series teaches how to overload your classes in PHP 4 by using the "overload()" PHP built-in function, in conjunction with the implementation of the "__set()", "__get()" and "__call()" methods, and explores the native support of object overloading in PHP 5.

They first take a step back and go over the concepts behind the property overloading from the previous part of the series. After being reminded of that (or hearing it for the first time for some), they translate that directly into a method for use on methods. And, with the help of a __call request, they show you how to make it all work together and overload the method call.
