PHP two-dimensional array time sorting implementation code

I discovered it yesterday when I was sorting the array. I wanted to sort by time, but PHP did not have this function built in, so I found this code online. The first parameter is the array, the second parameter is the element to be sorted, and the third parameter is the array. Each is the sorting method,

The following is the code for php two-dimensional array sorting

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");
