I've ported the Employee Admin Demo over to PHP using PHP-GTK for user interface. Not what most would expect from a PHP app, but it wouldn't be the same on the server side and I wanted the code to be as close to AS3 implementation as possible. If you want to try it and you're running Windows, the easiest way to get it working is to download a bundle from the PHP-GTK website simply unzip and run.
