Ajax breathes new life into web applications by transparently communicating and manipulating data in conjunction with a server-based technology. Of all the server-based technologies capable of working in conjunction with Ajax, perhaps none are more suitable than PHP, the world's most popular scripting language.

Beginning Ajax with PHP: From Novice to Professional is the first book to introduce how these two popular technologies can work together to create next-generation applications. Author Lee Babin covers what you commonly encounter in daily web application development tasks, and shows you how to build PHP/Ajax-enabled solutions for forms validation, file upload monitoring, database-driven information display and manipulation, web services, Google Maps integration, and more.

You'll also be introduced to other key topics like conquering cross-platform issues, countering potential security holes, and testing and debugging JavaScript with efficiency. All examples are based on real-world scenarios, so you'll be able to apply what you learn to your own development situations.

Industry Reviews

From the reviews:

"Within the hype of the Web 2.0 movement, Ajax is seen as a star technology. ... The book is well organized, and the author's writing is fairly easy to follow. ... For Ajax to work, the Web application user must be using a device capable of processing JavaScript, and JavaScript processing must be enabled. ... This book can help someone who wants to get a basic understanding of Ajax and PHP." (Will Wallace, ACM Computing Reviews, Vol. 49 (5), May, 2008)
