Whow, is that way of a loop really faster? I mean .. It looks as if the accept same thing happens - $upperlimit is set - $i counter is set - for every loop $i is set one higher - Also for every loop the expression ($i<$upperlimit) is evaluated.
Any idea on why it's faster? -----Original Message----- From: Chris W.

Unoptimized: $upperlimit = 100; for($i = 0;$i < $upperlimit; $++) { // your stuff } Optimized: $upperlimit = 100; $i = -1; while(++$i < $upperlimit) { // your stuff } Chris. -- Don't like reformatting your Outlook replies?
