Just to add to what jamesmc submitted. <? $a = array("item 1","item 2","item 3","item 4","item 5","item 6","item 7","item 8"); mt_srand ((float) microtime() * 1000000); # Replace the below line # $r = mt_rand(0,7); # with $r = mt_rand(0, sizeof($a)); print"Random Value for today is: $a[$r]"; ?> At least this way, you never have to know the length of an array.
