It never hurts to be overly cautious, but as MD5 hashes are strictly alphanumeric (using hex characters), you won't have an issue with injection with the code above. That is, of course, unless your version of PHP is rebuilt without MD5 hash support, or some other oddity that is on the outside edge of possibility. -- </Daniel P.
