Who Should Read This Book?

This book will appeal to the developer who is familiar with PHP and wants to learn how to use its OO capabilities. However, programmers already familiar with an OO language, such as Java, who want to learn a scripting language will also find it useful. Additionally, if you are a system administrator who is considering installing PHP 5, this book will help you make an informed decision.

PHP is first and foremost a language for creating dynamic web pages, but the relative simplicity of OOP in PHP makes it an ideal language for a general introduction to OOP. The concepts learned here are applicable to any OO language, so if you want to get a feel for OOP, OO PHP is a good place to begin.

Whatever your motivation, by the time you've finished this book you'll have an excellent understanding of OOP and numerous classes that can easily be reused in a variety of circumstances. But, more importantly, you'll be able to create your own classes and extend existing ones.
