A simple way to share a two-dimensional array ordering

PHP Code

  
   function Array_sort ($arr, $field, $by =sort_asc)    {                   foreach ($arr as $v) {              $r [] = $v [$field];            }         Array_multisort ($r, $by, $arr);         return $arr;    }    $array = Array (                     ´name´=>´ mobile ´,´brand´=>´ nokia ´,´price´=>3000),                      array (´name´=>´ laptop ´,´ brand´=>´lenovo´,´price´=>4000),                    );    $a =array_sort ($array, ´price´,sort_desc);    echo "
";    Print_r ($a);
