A small example of php sorting a two-dimensional array according to key value

/* Two-dimensional array is sorted by the specified key value
* $array array
* $key sort key value
* $type sorting method
* @edit: bbs.it-home. org
*/
function array_sort($arr, $keys, $type = 'desc') {
 $keysvalue = $new_array = array();
 foreach ($arr as $k => $v) {
 $ keysvalue[$k] = $v[$keys];
 }
 if ($type == 'asc') {
 asort($keysvalue);
 } else {
 arsort($keysvalue);
 }
 reset( $keysvalue);
 foreach ($keysvalue as $k => $v) {
 $new_array[$k] = $arr[$k];
 }
 return $new_array;
 }
