I think you should look at ImageMagik which is supported with PHP. I believe it has the capability to convert an image from CMYK to RGB. Not 100% sure:

Apparently it appears that their isn't an actual accurate algorithm to convert cmyk to rgb as pointed out by: http://developer.loftdigital.com/blog/cmyk-rgb-and-php

That was the first hit in the link I posted above and the author states

But all the ones I've looked at boil down the maths above, which isn't good enough any for serious design work

which would indicate they may be good enough for some uses. The only other option would be to have a full-featured image editor installed on the server and use command line functionality to convert the images.
