jQuery or PHP: Comparing Documents

Question

Just wondering if anyone can suggest a tool (either jquery or php) that allows document comparison? The documents are stored in MySQL (if that's relevant).

I've googled it, and found a couple of things (looks like there's something for jquery, but it's under development?). In any case, maybe my search terms aren't great, so, was hoping to get some suggestions...

EDIT Just as a follow-up... I wound up using http://code.google.com/p/google-diff-match-patch/wiki/API It's fast and simple!
