使用数字键对多维数组进行排序，但保持键相同，只需更改顺序

Question

所以我有 3 维数组。我希望该数组根据键重新排序，但键的值应保持原样。例如，如果数组键是 5,2,4,1,3，那么它应该变成 1,2,3,4,5。下面我提供了我拥有的数组和例外数组以及我尝试过的解决方案。

这是我拥有的数组：-

[5] => Array
        (
            [Anfield] => Array
                (
                    [0] => Array
                        (
                            [slot] => E3
                            [deal_text] => 
                            [units] => 5
                            [total_units] => 5
                            [amount] => 2620.8333333333
                            [is_freezed] => 
                            [can_sell] => 1
                        )

                )

        )
[2] => Array
        (
            [Anfield] => Array
                (
                    [0] => Array
                        (
                            [slot] => E4
                            [deal_text] => 
                            [units] => 1
                            [total_units] => 0
                            [amount] => 516.66666666667
                            [is_freezed] => 1
                            [can_sell] => 
                        )

                )

        )
[4] => Array
        (
            [Anfield] => Array
                (
                    [0] => Array
                        (
                            [slot] => C8
                            [deal_text] => 
                            [units] => 1
                            [total_units] => 0
                            [amount] => 526.66666666667
                            [is_freezed] => 1
                            [can_sell] => 
                        )
                )

        )
[1] => Array
        (
            [Anfield] => Array
                (
                    [0] => Array
                        (
                            [slot] => D4
                            [deal_text] => 
                            [units] => 1
                            [total_units] => 0
                            [amount] => 557.14285714286
                            [is_freezed] => 1
                            [can_sell] => 
                        )
                )
        )
[3] => Array
        (
            [Anfield] => Array
                (
                    [0] => Array
                        (
                            [slot] => E5
                            [deal_text] => 
                            [units] => 1
                            [total_units] => 0
                            [amount] => 516.66666666667
                            [is_freezed] => 1
                            [can_sell] => 
                        )

                )

        )

以下是我尝试过的解决方案：-

$result = ksort($result);
$result = array_values($result);
$result = array_splice($result, 0, 0);
$result = sort($result);
$result = array_splice($result, 0, count($result));

这是预期的数组：-

Array
(
    [1] => Array
        (
            [Anfield] => Array
                (
                    [0] => Array
                        (
                            [slot] => D4
                            [deal_text] => 
                            [units] => 1
                            [total_units] => 0
                            [amount] => 557.14285714286
                            [is_freezed] => 1
                            [can_sell] => 
                        )
                )
        )

    [2] => Array
        (
            [Anfield] => Array
                (
                    [0] => Array
                        (
                            [slot] => E4

                            [can_sell] =>

没有任何帮助将不胜感激。提前致谢。

Answer 1

您将ksort 用作$result = ksort($result);，ksort 返回 TRUE/FALSE。这意味着您将其分配给$results。 阅读这里PHP ksort

你的代码应该是：-

ksort($results);

而不是

$result = ksort($result);

您可以使用ksort 进行键排序，这是一个示例

$arr = [
  5 => [1,3],
  3 => [2,3],
  2 => [0,7]
];
ksort($arr);
echo '<pre>';
print_r($arr);

输出

Array
(
[2] => Array
    (
        [0] => 0
        [1] => 7
    )

[3] => Array
    (
        [0] => 2
        [1] => 3
    )

[5] => Array
    (
        [0] => 1
        [1] => 3
    )

  )
