Despite such a low version number, a good chunk of functionality is implemented. Use the link below for the full announcement. 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. The documentation is fairly non-existent at the moment, but most of the things should be obvious from the included examples.
Feedback is welcome.
The following comments are owned by whoever posted them. It becomes harder to find the right scripting language. There are just too many. Many make investments in language and will prefer to do everything with it. PHP-programmer is therefore now given access to cool GUI without having to learn say, Python.
