with this third party code function rank($input) { $output = array(); $ranking = $input; sort($ranking); $ranking = array_flip($ranking); $last_val = -1; foreach($ranking as $key => $val){ $repetitions = ($val-$last_val-1); $last_val = $val; if($repetitions) { $ranking[$key] = (($val*($repetitions+1))-($repetitions+1)*(($repetitions)/2))/($repetitions+1)+1 ; } else { $ranking[$key] = $val+1; } } foreach($input as $key => $val){ $output[$key] = $ranking[$val]; } return $output; } $a = array(4,76,34,13,34); $c = rank($a); print_r($c); that ranks an array, how could i tweak it to rank the other way round, so the highest value = 1, etc? thanks
