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. PHP used to be one of the hottest web technologies in the IT, now add Ajax to it, and you have a winner. I have heard that there is no way you are going to be without a considerably high paying job if you know PHP and AJAX. Not a PHP person? That’s fine. You can always pick up Ajax on Java. If you are really into new technologies, you might want to order ASP.Net 2.0 Web Parts in Action: Building Dynamic Web Portals. It’s coming out in a day or two.
