If your server has the appropriate programs installed, there ARE some command line utilities that can take a PDF and convert it to another form; You can execute them with an exec call. Theoretically, if the PDF is corrupt they will print out some kind of error which you can capture.
It could also take up a ton of processing power if you do a lot of this, so be careful on the implementation. (o: I don't know if this is an option for you or not, but it is something that was done at my last company to verify that uploaded PDFs were at least readable by -something-. For Linux there is pdf2ps, and iirc there is some other program out there that just pulls out the text.

Thanxs very much guys! I do realize that it is not foolproof, but better than nothing. In my situation mime_content_type doesn't work, so I will have to settle for the other method.
