I would like to quickly set up a RESTful site using PHP without learning a PHP Framework. I would like to use a single .htaccess-file in Apache (no mod_rewrite) or a single rule using Nginx, so I easyli can change web server without changing my code.

So I want to direct all requests to a single PHP-file, and that file takes care of the RESTful-handling and call the right PHP-file.

In example:

1. The user request http://mysite.com/test
2. The server sends all requests to rest.php
3. The rest.php call test.php (maybe with a querystring).

If this can be done, is there a free PHP-script that works like my rest.php? or how can I do this PHP-script?
