This book is an essential guide to some of the best free add-ons to PHP. These add-ons provide invaluable functionality for improving your PHP Web applications, including accessing databases, generating robust Web forms, using page templating systems, creating and parsing XML documents, authenticating users, and much more.Because many of the tools covered in this book have skimpy or nonexistent documentation, Sklar provides plenty of information about installing, configuring, and using each tool, along with tons of examples written with both PHP 4 and PHP 5 in mind.No need for you to code your own authentication system or Web form construction set: Sklar has laid out the details of Auth and HTML_QuickForm, two PEAR modules that do the job for you. Also, chapters on debugging your programs and how to increase your Web server speed will help you to eliminate some inefficiencies in PHP and enhance performance without any code modification. «
