I have expanded on this further, found a tastier name and now have a project page up http://projects.cyberlot.net/trac/jqpie/wiki. Added an cheesy jQuery/Interface autocomplete example although I would of preferred a json approach to the xml but it works never the less.

The jQPie project provides a way to link Javascript and PHP easily through the jQuery library with simple requests to use things JSON statements and direct output in your Javascript application.

This is a simple php handler, it doesn't try to generate javascript for you, honestly if your using jquery you better already be able to write your own javascript ;).

The goal is to provide a extremely simple way to call php functions from within javascript and either get data back, inject php generated html or call jquery functions from php.

You can check out his demo here - three simple examples showing how to get JSON values, inject HTML, and some more complex work with Javascript and CSS.
