PHP 5 Objects, Patterns, and Practice - Programmer Books

PHP 5's object-oriented enhancements are among the most significant improvements in the 10 year history of the language. This book introduces you to those features and the many opportunities they provide, as well as a number of tools that will help you maximize development efforts. The book begins with a broad overview of PHP 5's object-oriented features, introducing key topics like a class declaration, object instantiation, inheritance, and method and property encapsulation. You'll also learn about advanced topics including static methods and properties, abstract classes, interfaces, exception handling, object cloning, and more. The next part of the book is devoted to a topic that is often a natural extension of any object-oriented introduction: design patterns.
