Now that PHP 5 effectively incorporates object orientation, developers need to know how to take advantage of these new features. Working within the context of concrete examples, this book begins with code compatible with PHP 4 and 5, and then focuses on object orientation in PHP 5. The author's practical approach uses numerous code examples, which will help developers get up to speed with object oriented PHP quickly, and show them how to apply what they learn to everyday situations. All code samples are available for download on the book's companion site.
