arranging type of architecture work better...

$players = array(     array(         "name" => "l337 h4x0r",         "score" => 10432,         "ping" => 0.35     ),     array(         "name" => "el kabooom",         "score" => 19918,         "ping" => 0.45     ),     array(         "name" => "kapop",         "score" => 10432,         "ping" => 0.38     ) ); 

then more efficiently sort multi-dimensional array, , retrieve $lowestscore , $highestping values.

$playersscore = subval_sort($players,'score');  $lowestscore = $playersscore[0]['score'];  $playersping = subval_sort($players,'ping');  $highestping = $playersping[ count($players)-1 ]['score'];  function subval_sort($a,$subkey) {     foreach($a $k=>$v) {         $b[$k] = strtolower($v[$subkey]);     }     asort($b);     foreach($b $key=>$val){         $c[] = $a[$key];     }     return $c; }
