In an effort to share the knowledge with the entire community, the Bruce Perens' Open Source Series has posted a PDF copy of one of the latest offerings from Prentice-Hall - PHP 5 Power Programming (Gutmans, Bakken, Rethans).

In this book, PHP 5's co-creator and two leading PHP developers show you how to make the most of PHP 5's industrial-strength enhancements in any project - no matter how large or complex. Their unique insights and realistic examples illuminate PHP 5's new object model, powerful design patterns, improved XML Web services support, and much more. Whether you're creating web applications, extensions, packages, or shell scripts, or migrating PHP 4 code, here are high-powered solutions you won't find anywhere else.

Thanks to Derick Rethans for pointing out this link to the fine book he worked on...
