While Flash and Java have traditionally been the leaders in this field, JavaScript is a strong contender, and it
plays nicely with PHP. ExtJS is a JavaScript framework that allows developers, including PHP developers, to
build responsive and intuitive RIA interfaces with the power of AJAX. Beginning PHP RIA using ExtJS offers an introduction to building RIAs with ExtJS, geared specifically for PHP developers. Learn how to build familiar-looking interfaces, move data to the interface smoothly using PHP, and debug your RIA to eliminate user
interface issues.
