This Cookbook has a wealth of solutions for problems that PHP programmers face regularly. With topics that range from beginner questions to advanced web programming techniques, the "PHP Cookbook", 2nd Edition contains practical examples -- or "recipes" -- for anyone who uses this scripting language to generate dynamic web content. Updated and revised for PHP 5, this book provides working solutions that explain how to use the new language features in detail, including the vastly improved object-oriented capabilities and the new MySQLi database extension. New sections on classes and objects are included, along with new material on processing XML, building web services with PHP, and working with SOAP/REST architectures. With each recipe, the authors include a discussion that explains the logic and concepts underlying the solution.
