From Leon Pegg on the PHP-GTK Community site:

I have been working on the php-gtk documentation the last few weeks. I finally have an updated version of the manual. Unfortunately its not on the main site gtk.php.net, so I have uploaded it here: leonpegg.com/php-gtk-doc

The manual includes tutorials, the actual reference guide and an appendix of details on terms/other information.

You know when you reach that point when you just don't remember where to configure your Zend Platform Events, how to set up your Tunneling, or what that Zend Core extension does? Well the documentation team at Zend have come up with a way to make all Zend product documentation as easily available as possible, so you can all benefit from our wisdom and experience.

The documentation center is a resource for all things Zendy - information on their products made searchable and easy to browse.

Every so often I try to use PDO under PHP5, and every time I run in to basic functionality problems with no ability to find out what's going on under the hood.

He includes a few comments supporting his statement including an issue where a prepare() call didn't work, his frustration with not being able to see what's "under the hood" and the lack of documentation to help with these sorts of issues.

With a ton of help from Andy Dawson (AD7Six) the documentation for CakePHP 1.2 has moved forward immensely with the unveiling of the CakePHP Cookbook. It's a combination of manual and wiki, where people can flesh out the manual and make comments on the methods in there.

With the wiki in place, anyone can add to the communal CakePHP wisdom (or correct where others might have strayed) to make it a bigger and better resource for the whole range of CakePHP developers.
