Getting Started with Objects with PHP V5

With limited space available, it has not been possible to cover everything. There are two directions to take in further research: One should yield breadth and the other depth. By breadth, I mean the features that were beyond the scope of this article, such as abstract classes, interfaces, the iterator interface, reflection, exceptions, and object cloning. By depth, I mean questions of design. While it is important to understand the range of tools available in PHP for object-oriented programming, it is equally crucial to consider how best to work with such features. Fortunately, there are many resources available that focus on patterns of design in an object-oriented context (see Resources).
If you are still programming with PHP V4, I hope you found enough new features to justify migrating to V5 and its core object-oriented features. You'll soon wonder how you managed without them.
