PHP Two-dimensional array time ordering implementation code

Yesterday to sort the array of time to find, to sort by time, but PHP did not have this function, so found on the Internet this code, the first parameter is an array, the second is to sort the elements, the third is a sort of way,

Here is the code for PHP two-dimensional array ordering

function ArraySort ($arr, $keys, $type = ' asc ') {    $keysvalue = $new _array = Array ();    foreach ($arr as $k = + $v) {      $keysvalue [$k] = $v [$keys];    }    $type = = ' ASC '? Asort ($keysvalue): Arsort ($keysvalue);    Reset ($keysvalue);    foreach ($keysvalue as $k = + $v) {      $new _array[$k] = $arr [$k];    }    return $new _array;  } $arr [] = Array ("name" = "1", "Time" =>1), $arr [] = Array ("name" = "2", "Time" =>2), ArraySort ($arr, "Time", " Desc ");
