usort不适用于laravel多维数组

Question

我有一个阵列

Illuminate\Support\Collection Object
(
    [items:protected] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 79
                    [name] => shelin
                    [status] => 0
                )

            [1] => stdClass Object
                (
                    [id] => 80
                    [name] => shanu
                    [status] => 2
                )

            [2] => stdClass Object
                (
                    [id] => 81
                    [name] => linto
                    [status] => 2
                )

            [3] => stdClass Object
                (
                    [id] => 82
                    [name] => joseph
                    [status] => 0
                )

        )

)

我想通过状态desc顺序重新排列这个数组我尝试

usort($usersdetailsA, function($a, $b) {
    return $a->status <=> $b->status;
});

我得到了一个错误

usort（）期望参数1是数组，给定对象

我试过$ usersdetailsA = $ this - > $ usersdetailsA-> getValues（）;我得到了一个错误

未定义的属性：TCG \ Voyager \ Http \ Controllers \ Users :: $ [{“id”：79，“name”：“shelin”，“status”：0}，{“id”：80，“name”：“ shanu”， “状态”： “2”}，{ “ID”：81， “名称”： “linto”， “状态”： “2”}，{ “ID”：82， “名称”： “约瑟夫” “状态”：0}]

预期产出

Illuminate\Support\Collection Object
    (
        [items:protected] => Array
            (
                [0] => stdClass Object
                    (
                        [id] => 80
                        [name] => shanu
                        [status] => 2
                    )
 [1] => stdClass Object
                    (
                        [id] => 81
                        [name] => linto
                        [status] => 2
                    )

                [2] => stdClass Object
                    (
                        [id] => 79
                        [name] => shelin
                        [status] => 0
                    )



                [3] => stdClass Object
                    (
                        [id] => 82
                        [name] => joseph
                        [status] => 0
                    )
Any help would be appreciated.Thanks in advance

你可以用给定的密钥用collection方法对sort进行排序：

$sorted = $collection->sortByDesc('status');
