Question

我有一个多维关联数组，其中每个节点可以有可变数量的子节点。每个子节点将在某个点以一个布尔节点结束。我想要做的是，如果所有子节点都以false结尾，则父节点将从数组更改为布尔值false。

示例输入数组：

[
    [Agronomy] => [
        [blendingAnhydrous] => [
            [blendingSprayOrdersDeliveryTkts] => [
                [add] => true,
                [create] => true,
                [inquire] => true,
                [delete] => true
            ],
            [historyInquiry] => [
                [add] => false,
                [create] => true,
                [inquire] => false,
                [delete] => true
            ],
            [listAnhydrousTicketsToBeBilled] => [
                [add] => false,
                [create] => false,
                [inquire] => false,
                [delete] => false
            ],
        ],
        [main] => [
            [agronomyBlendingAnhydrousEntry]: false,
            [agronomyRecomendationsHistory]: false,
            [agronomyReports]: false,
            [agronomySetup]: false
        ],
    ],
    [Grain] => [
        [main] => [
            [option1] => false,
            [option2] => false,
            [option3] => false,
        ]
    ]
]

所需的输出数组：

[
    [Agronomy] => [
        [blendingAnhydrous] => [
            [blendingSprayOrdersDeliveryTkts] => [
                [add] => true,
                [create] => true,
                [inquire] => true,
                [delete] => true
            ],
            [historyInquiry] => [
                [add] => false,
                [create] => true,
                [inquire] => false,
                [delete] => true
            ],
            [listAnhydrousTicketsToBeBilled] => false
        ],
        [main] => false
    ],
    [Grain] => false
]

我到目前为止尝试过的代码：

function collapseAuthorities(&$complexArray)
{
    $keepExpanded = false;
    foreach ($complexArray as $node => $value) {
        if (is_array($value)) {
            $this->collapseAuthorities($value);
            if (!$keepExpanded) {
                $value = false;
            }
        } elseif ($value === true) {
            $keepExpanded = true;
        }
    }
}

我已经经历了很多关于多维数组的SO问题，但是没有找到任何可以解决这个问题的方法。

您需要递归扫描$ values：

$rewriteArray = array();
foreach($mainParentArray as $key=>$value) {

    $rewriteArray[$key] = decompose($value);

}

function decompose($value) {
    if (is_array($value)) {
        list($array_as_value, $false_found) = keyScan($value);
        if ($array_as_value) {
            dendriticReconstruct($value);
        } else {
            $return = $false_found ? false : $value;
        }
    } else {
        $return = $value;
    }
    return $return;
}

function keyScan($value) {
    $array_as_value = $false_found = false;
    foreach($value as $k=>$v) {
        if (is_array($v)) {
            $array_as_value = true;
            break;
        } else {
            if ($v === false) {
                $false_found = true;
                break;
            }
        }
    }
    return array($array_as_value, $false_found);
}

function dendriticReconstruct($value) {

}

我不能完成它 - 这花了我太久了。我希望这能让你开始朝着正确的方向前进！

折叠多维关联数组，以便在所有子节点都为false时将节点转换为false
