I'm trying to take 2 versions of text (10 pages long) and compare the 2 to produce the difference. I know Wikipedia has a similar feature to compare revisions. Does anyone know what they use? I'm hoping they're using a php-driven solution.

There is an implimentation of diff in php. I havent used it but it's a start. There is also something called PHP inline diff that you can check out
