I've had this problem.  I have no idea how you'd do it in code, when I've needed to do it I read the .prj file, find some kind of descriptive text (for example "iowa north"), then search for it here:

http://spatialreference.org/ref/epsg/?search=iowa+north&srtext=Search

I try to match up corresponding numbers (like standard_parallel, latitude_of_origin, etc).  Oh, match feet/meters too.

It's usually pretty simple to do by hand.  Is that an option or do you need code for this?
