根据多维数组中某一键值对多维数组进行排序

• 用到的方法：array_multisort

  $data=array(
      0=>array('one'=>34,'two'=>'d'),
      1=>array('one'=>45,'two'=>'e'),
      2=>array('one'=>47,'two'=>'h'),
      3=>array('one'=>12,'two'=>'c'),
      4=>array('one'=>15,'two'=>'w'),
      5=>array('one'=>85,'two'=>'r'),
  );
  foreach($data as $val){
      $key_arrays[]=$val['one'];
  }
  array_multisort($key_arrays,SORT_ASC,SORT_NUMERIC,$data);//
  var_dump($data);

• 输出结果
