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 new features and the many opportunities they provide, as well as a number of tools that will help you maximize development efforts.
Chapter 8 -- Some Pattern Principles -- of PHP 5 Objects, Patterns, and Practice covers four basic topics: decoupling, composition, pattern categories and the power of the interface.
