如何使用 PHP foreach 循环（或不使用）来重构关联数组？

Question

所以这是名为 $results 的关联数组的第一个键：

[
    10 (2) => [
        step (3) => [
            0 (1) => [
                id => 1
            ],
            1 (1) => [
                id => 2
            ],
            2 (1) => [
                id => 3
            ]
        ],
        status (3) => [
            0 (1) => [
                id => 2
            ],
            1 (1) => [
                id => 4
            ],
            2 (1) => [
                id => 10
            ]
        ]
    ],

我想重组它，使其看起来像这样：

[
    10 (2) => [
        step (1) => [
            0 (1) => [
                id => 1
            ],
        status (1) =>[
            0 (1) => [
                id => 2
            ],
        step (1) => [
            0 (1) => [
                id => 2
            ],
        status (1) =>[
            0 (1) => [
                id => 4
            ],
            
          AND SO ON...

简而言之，我只想将步骤和状态显示为每一步的一对，并导致 [step, status]、[step, status]、[step, status]... 关联大批。现在数组更像是 [step, step step], [status, status, status].

这是我最初的 foreach 循环，它首先为我提供了数组：

$results = [];

        foreach ($entities['node'] as $nodeIdBis => $nodeWkf) {

            $nodeWkfTmp = ["step" => [], "status" => []];
            
            foreach ($nodeWkf as $wkfId => $subNodeWkf) {

                foreach ($subNodeWkf as $stepId => $nodeStatus) {

                    $nodeWkfTmp["status"][] = ["id" => $nodeStatus['statusId']];
                    $nodeWkfTmp["step"][]  = ["id" => $stepId];
                }
            }
            $results[$nodeIdBis] = $nodeWkfTmp;
        }

非常尊重谁会找到诀窍:)

只需更改 $nodeWkfTmp 数组赋值即可获得对数组 [step, status]:

$nodeWkfTmp = [];

$nodeWkfTmp[] = [
  "status" => ["id" => $nodeStatus['statusId']],
  "step"   => ["id" => $stepId]
];
