Your only other option would be to troll through /tmp looking for PHP session filenames that match the session ID or whatever, and then searching your database for IDs that aren't listed in there, and... You'd probably end up with a race condition sooner or later, and this would be dog-slow if you have lots of visitors, and you really don't want to do it this way. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
