uniqid() yields truly unique values for a single machine (except for CYGWIN, and potentially older Windows versions), if $more_entropy is FALSE[1]. Of course, the function shouldn't be used for any crypto purposes, but it is fine to get a unique ID if you have no database that delivers a sequential index number (aka. autoincrement field), for instance.
