The assignment operator (=) computes the right-hand side completely before putting its value in the left-hand side. Your large arrays might get dumped to swap on the hard drive and burn pits into the platters, and they might thrash the CPU until it catches on fire, but there's no race condition in this statement. -- 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
