PHP数组自定义排序

Question

$order = array('1', '4', '3', '5', '2', '0');
$array = array(
  '0' => 1231,
  '1' => 12321,
  '2' => 12321,
  '3' => 12321,
  '4' => 12321,
  '5' => 12321,
);

$array2 = array();
foreach ($order as $key=>$value) {
   $array2[$value] = $array[$key];
}

var_dump($array2);

有没有更好的方式处理这种自定义排序

Answer 1

print_r(array_combine($order,$array));

Answer 2

$array = array_map(function($val) use ($array){ return $array[$val];},$order);
