From Engadget today, there's a look at how you can, using a PHP installation and some scripts, control iTunes from any web browser.

For today’s how-to we’re going to set up a simple web server in XP so that we can control iTunes remotely. Engadget reader Jordan Parker was tired of having to walk into the other room to change tracks so he put together the PHP script we’ll be using. The page it generates should be usable on any device with a web browser. Similar solutions exist for OS X. Click on to get the full skinny — it’s worth your time, promise!

They give you a zip file of all of the images and PHP scripts you'll need. They then walk you through the installation of PHP on WinXP, using something called BRS WebWeaver as the server. Then you start it all up, head over to the player.php script, and, if all went well, you'll have a working iTunes interface.
