You can use a combination of mt_rand(), array_push() and in_array() to get few unique randum numbers out of small range of numbers ( eg: 1-10 ). Otherwise you would get dups when dealing with small ranges. <?php function random_number($min, $max) { return mt_rand($min, $max); } $wins = array(); while ( count ( $wins ) < 3 ) { $value = random_number(1,10); if (in_array($value, $wins)) { continue; } array_push($wins, $value); } echo $wins[0]." ". $wins[1]. " ".$wins[2]; ?> -- http://www.php.net/manual/en/function.mt-srand.php http://master.php.net/manage/user-notes.php?action=edit+16986 http://master.php.net/manage/user-notes.php?action=delete+16986 http://master.php.net/manage/user-notes.php?action=reject+16986
