Asynchronous JavaScript and XML (Ajax), has become the most popular new Web development technology. This is the first of a new two-part "Developing PHP the Ajax way" series (2nd part is not posted yet). In this Ajax tutorial and coding demonstation, you'll develop an online Web photo album application using PHP and the Simple Ajax Toolkit (Sajax). It starts be coding a simple photo album app using the usual method of PHP programming, to which Sajax is then applied and used to create it into an active Web application.

This tutorial article teaches the reader how to develop a simple photo album using two methods: a traditional Web application and a Sajax-powered application. The PHP album application reads the contents of a directory, displaying a thumbnail table to the user. When the user selects a thumbnail, the image expands to full size. Because a traditional application is being coded, every click generates a new HTTP request, and parameters are sent within the URL.
