PHP 数组按指定的键值排序

需求：按照用户的 rank 从小到到排序（PHP 按照二维数组指定的键值排序）。

$users = [
   [ 'id' => 1, 'rank' => 3 ],
   [ 'id' => 2, 'rank' => 1 ],
   [ 'id' => 3, 'rank' => 2 ],
];
array_multisort(array_column($users, 'rank'), SORT_ASC, $users);

输出结果：

Array
(
    [0] => Array
        (
            [id] => 2
            [rank] => 1
        )

    [1] => Array
        (
            [id] => 3
            [rank] => 2
        )

    [2] => Array
        (
            [id] => 1
            [rank] => 3
        )

)
