You forgot the URL: xajax PHP Class Library - The easiest way to develop asynchronous Ajax applications with PHP

I've seen this library before but personally, I prefer doing all AJAX stuff myself. Some time ago I was using AJAX in the admin panel of the system I had designed. In the user management pane you could browse/add/edit/delete users all via AJAX, without reloading the page. Browsing users was the most tricky cause the script downloaded a list of users (id, name, email, level etc) and had to dinamically build the HTML table with that information, I don't know if you can do this kind of thing using a library like XAJAX.
