The main PHP website has announced the release of the new documentation build system (as Hannes Magnusson mentioned previously) is ready and has been launched for testing.
The PHP documentation team is pleased to announce the initial release of the new build system that generates the PHP Manual. Written in PHP, PhD ([PH]P based [D]ocBook renderer) builds are now available for viewing at docs.php.net. Everyone is encouraged to test and use this system so that bugs will be found and squashed.
Once the new build system is stable, expect additional changes to the PHP manual that will include an improved navigation system and styling for OOP documentation.
You can use the my.php page to set it as your default mirror if you'd like to use it seamlessly.
