DevShed has posted part one of a new pair of articles that show how to use inheritance in your PHP applications.

In the two articles in this series I'm going to show you how to build a sample object-based web site from its bare bones structure, by using the encapsulated logic of some parent and child PHP 5 classes. In this way I'll demonstrate how inheritance can be used to tackle a concrete project, such as constructing dynamic web pages.

In part one, they build the foundation of their sample application - a web page builder - by defining the WebPage class and abstract methods for it like buildHeader, buildStyles and buildBody. Inheriting from this, they build a HomeWebPage class that defines the methods and values to create a simple page. They take it even a step further and build an AboutUsWebPage to show another implementation.
