Most scripting languages have nice DBF interface modules already so we elected to leverage those instead of writing one. So, you'd need to find your favorite for PHP and use that to initialize a table and add records. It's probably just a few additional lines of code as you've done most of the hard work already.
Also, any one willing to help with documentation would be most welcome! (Should take that offer to mapserver-dev...)
