PHP has become even more powerful as a Web development tool with the addition of two new modules -- PHP-GTK and PEAR::DB. Advanced PHP for Web Development fills a void in the PHP book market for an advanced-level book showing how to create complex Web sites. The authors create custom graphics using PHP-GTK to make application interfaces more intuitive to users. They also show how to create Web applications that are database independent -- not relying on MySQL or MS SQL, or Oracleusing the new PEAR::DB module! Through working code examples and applications, Cosentino takes readers through intermediate tasks that will have an impact on the usability of their Web site, including how to create friendlier forms and use different user-authentication themes. Later sections of the book take readers through more complex code examples and applications, so that, by the end of the book, the reader will be armed with the skills (and working code) to create powerful PHP-backed Web sites!

The goal of this book is to help you get a better grasp of PHP, to learn some of the less commonly used features, and to help you build some applications that are useful in your work or hobbies. I hope it gives you some ideas on how to make your own applications easier to code and easier to use.Who This Book Is For
This book is for those who have done some basic PHP programming and wish to learn about some of the more advanced techniques to make applications easier to use and easier to program.
I received many emails from across the globe from readers of my first book, Essential PHP for Web Professionals (also published by Prentice Hall), who liked the concise style and ample examples I had provided. I received literally dozens of emails from people who said they had read other PHP programming books, but they didn’t really grasp how PHP worked until they read my book. I can’t tell you how happy that makes me feel. I hope to do the same with this book.
This book is for those of you who are ready to take the next step and learn a little more about PHP. This book isn’t a reference book, nor does it cover every advanced aspect of PHP. It does, however, stretch beyond the basics and introduce some more concepts that can help you with your PHP programming.Getting the Code
