If you have seen true object-oriented development, and have had trouble using these concepts in PHP; don't despair any longer. Matt (Zandstra) has done all the work for you--all you need is a weekend or two to do a little reading. While being an easy read, Zandstra's introduction to the object-oriented features is, I believe, perfectly adequate to get started with object-oriented PHP programming.
PHP 5 Objects, Patterns, and Practice is a practical design and management book devoted to exploring object-oriented programming in PHP 5, the latest and most powerful version of PHP. Using a wide variety of pattern examples, this insightful text explores the principles underlying design patterns, focusing largely on those patterns collected by the "Gang of Four." Veteran author Matt Zandstra further addresses the needs of PHP users by providing practice and examples on topics including unit testing, documentation, version control, and automated building.
