After briefly explaining what PHP is and how it integrates with HTML, David guides you through the setup and configuration of a PHP development environment on both Windows and Mac OS X. He also introduces the features of the PHP language through a series of hands-on exercises before embarking on a larger project that involves building a script to validate and email user input from an online form.
