Jake Blauzier has just posted the last part of his series focusing on the creation of an event-based Ajax framework that works with PHP. It allows for calls to static functions, can return Javascript representations of PHP objects and a "call queue" system to keep things from overlapping.

Here's the list of the parts of the series:

• Part 1 - introduction, sample usage
• Part 2 - problems in making an event-based ajax callback model (and his solutions)
• Part 3 - the use of JSON in the framework
• Part 4 - implementation of the Scriptifiable interface
• Part 5 - implementing the Remotable interface

You can download the latest version of his Ajax framework directly from his blog.
