That's a bad method. You have to have the lock around the read and the write. With your method, 5 users might read the file, all getting 99 for the count, and then each one will try to seperatly write 100 to the file. So you lose 4 actual counts. You want to open the file, read it, update value, write it, unlock, and close the file. Using multiple files would just be a waste of space in my opinion. A locked file doesn't stop the script, it simply waits for the file to be unlocked and then continues on. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
