Gosh!!!
AJAX = Asynchronous Javascript And XML
If you don't use XML, i believe you can't say that you use ajax, right??
We can emulate that effect (without post data) with dom and other in javascript. I have a javascript function that do this (function_name(div_to_show, param, php_backend_file)). And is not an ajax function!!
Scriptaculous/Prototype, JQuery, Xajax are frameworks to work better/faster to ajax.
Codeigniter, Cake, Symphony, ZF, Prado are frameworks to work better/faster to php.
