On the PHPClasses.org blog today there's a new post showing how you can use PHP-GTK to generate websites, not just the more traditional desktop applications people associate it with.

es, you read it right, GTK+, the Gnome Toolkit library, normally used to create desktop applications, can now be used to serve the same applications via the Web to a browser that supports HTML 5 canvas objects. PHP-GTK is a PHP extension that uses the GTK+ library to build PHP desktop applications. So it can eventually benefit for this GTK library enhancements to build PHP-GTK based applications that can be served over the Web to HTML 5 browsers.

Manuel starts by explaining a bit about what PHP-GTK (and GTK+) is and a recent update to GTK+ that allows it to generate output to different backends - Wayland (direct graphics rendering) and Broadway (HTML5 canvas support). There's no example code to go along with the post, but there's a good description of how the output of an X Windows session could be pulled in and displayed in a browser (see this video for a cool example using GIMP and Broadway).
