我从mysql数据库中提取数据.我想添加多次运行的长度,并按运行最远的人的等级对它们进行排序.

    function determineLength($db, $name){
      $getLength = "select length from $db where name = $name and sex = 'male'";
      $gettingLength = mysql_query($getLength);
      while($gotLenth = mysql_fetch_array($gettingLength)){

      more code that calculates total length and returns it as $lengthAccumulator 
      }
      return array('totalLength'=>$lengthAccumulator);
    } 

现在,我有30个不同的男性,他们的名字永远不会改变,我需要拉动和排序.如何在没有冗余的情况下为每个人运行mysql代码？我只能想出这种方式 -

    $name = john;
    $a = determineLength($db, $name);
    $aLength = $a['totalLength'];

    $name = sam;
    $b = determineLength($db, $name);
    $bLength = $b['totalLength'];

    $name = henry;
    $c = determineLength($db, $name);
    $cLength = $c['totalLength'];

    $name = ted;
    $d = determineLength($db, $name);
    $dLength = …
