PHP-GTK. Anyone who uses Linux often enough probably recognizes the two acronyms there. It sounds like a gift from the deity of choice to anyone who uses the PHP language frequently. PHP (Hypertext Preprocessor) as it stands to most people is one of the most common programming languages used today… on the web. Most are familiar with the need to have a web server with PHP so applications like forums and blogs can be run. The funny thing is that 99% of the people using PHP have no idea it really has nothing to do with Apache (the most common web server application), or that PHP does not even need a web server to run.
