1. PHP extension for GTK+ client-side cross-platform GUI apps. PHP-GTK: PHP language bindings for GTK+ toolkit PHP-GTK is a PHP extension that enables you to write client-side cross-platform GUI applications. This is the first such extension of this kind and one of the goals behind it was to prove that PHP is a capable general-purpose scripting language that is suited for more than just Web applications. This extension will _not_ allow you to display GTK+ programs in a Web browser, and can be used in the Web environment only if you are running the webserver locally. It is intended for creating standalone GUI applications. From Debian 3.0r0 APT
