AjaxLine

PHP-Ext is an open source widget library written for PHP 4 and 5 to empower the UI Layer.
It is based on ExtJS JavaScript widgets which provide a standard and powerful API to build Rich Internet Applications. It basically works as a convenient wrapper for the Ext JS Javascript Objects.

Among other features, PHP-Ext provides useful and common controls to create forms, rich comboboxes, powerful grids and menus. It also promotes the use of JSON and XML client/server communication to populate forms and grids using Ajax. Additionally it has a Javascript helper to ease the javascript code generation and use.
