Zandstra M. PHP objects, patterns, and practice

2 edition. — Apress, 2007. — 487 p. — ISBN-13: 978-1590599099.In the three years since the release of PHP 5 (and, incidentally, of the first edition of this book), developers in the PHP community have driven objects and patterns ever further into the mainstream. The PHP language has itself matured, accommodating a steady stream of enhancements. At the same time, tools for testing and integration have continued to improve.
During this period, I’ve been delighted to hear from readers who found the book useful in their projects. I’ve even been told of a few aha! moments in which the whole seeming mess of objects, patterns, classes, and components clicked into focus, became elegant. This is a particular pleasure, since it’s for moments like these that I started to write in the first place.
Most computer books have a limited shelf life. Even when the core concepts they describe remain sound, their powers begin to wane once more than a few of their code examples no longer run. That’s why it’s time for a new edition of PHP Objects, Patterns, and Practice.
I have updated and tested every code example against recent versions of PHP (including, where possible, what there is of PHP 6). I have also described more patterns and upgraded many of the chapters concerned with integration tools. There is also a brand new chapter on testing with PHP Unit.
I hope that this updated and improved edition will continue to help PHP developers to do amazing things using objects and patterns!
