If you absolutely must have an array that large (and I'd love to know why you do) then it's going to have to be held in memory by PHP for the entire duration of the script. 380,000 items even at a few KB each is hell of a lot of overhead. I'm impressed PHP managed it, let alone at 9 hours to process :) -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
