Yet another PHP framework can be added to the lists already out there - Simplicity:

The Simplicity PHP Application Framework is an advanced, scalable and extensible PHP application framework to aid developers in creating high traffic, high availability Web 2.0 online applications. Integrating a solid MVC framework with some of the best Open Source projects around Simplicity aims to assist developers with any amount of experience in taking their applications to a new level.

As mentioned on the Ajaxian post about the framework, there's an Ajax admin console that lets the developer configure everything in their app including database info, creation of controllers and drop-in predefined actions.
