PHP Desktop
Develop desktop GUI applications using PHP, HTML5, JavaScript
...The development workflow you are used to while creating web applications remains the same, there is no new framework / API to learn. The process of turning an existing website into a desktop application is basically a matter of copying it to the directory. In a certain sense phpdesktop acts as a PHP to EXE compiler. It embeds a web browser, a multi-threaded web server and a PHP interpreter.
