Very true, but the double md5_hex() doesn't hurt (as far as I know).

As I said, I am no crypto expert, and my knowledge of these things is limited. But I would think that hashing a reasonably unique string to produce a pretty darn close to unique string, and then hashing it again to get (what I would assume is) an even closer to truely unique string is a good thing when generating session ids. Please though, if I am wrong, and the double hash provides no benefit let me know why, as I would be interested in knowing.
