With the release of PHP 5 web developers need a guide to developing with PHP 5 to both learn its complex new features and more fully implement the long-standing features on which PHP s success is built. PHP 5 in Practice is a reference guide that provides developers with easy-to-use and easily extensible code to solve common PHP problems. It focuses on providing real code solutions to problems, allowing the reader to learn by seeing exactly what is happening behind the scenes to get your solution.
