Intended Audience

This book is targeted at developers of an intermediate or advanced level who already have a fair amount of comfort programming with PHP 5. You should be aware of object-oriented programming principles such as inheritance, abstraction, and encapsulation as well as how these principles relate to the PHP 5 object model. The book will detail general concepts and use PHP as a (very qualified) means to the end of illustrating these concepts with practical examples. Knowledge of the HTTP protocol, XML concepts and related PHP extensions, or lavaScript will also prove particularly helpful.
