如何从API返回的嵌套JSON数组中提取指定分组数据？

我尝试了多次仍无法解决这个问题，需要帮助：

API返回的嵌套数组结构如下：

Array
(
    [group] => Array
        (
            [name] => Iedereen
            [desc] => Iedereen
            [type] => G
            [instituteNumber] => Array
                (
                )
            [children] => Array
                (
                    [group] => Array
                        (
                            [0] => Array
                                (
                                    [name] => Beheerders
                                    [desc] => Beheerders
                                    [type] => G
                                    [code] => Beheerders
                                    [instituteNumber] => Array
                                        (
                                        )
                                )
                            [1] => Array
                                (
                                    [name] => Personeel
                                    [desc] => Personeel
                                    [type] => G
                                    [code] => Personeel
                                    [instituteNumber] => Array
                                        (
                                        )
                                    [children] => Array
                                        (
                                            [group] => Array
                                                (
                                                    [0] => Array
                                                        (
                                                            [name] => DT
                                                            [desc] => directieteam
                                                            [type] => G
                                                            [code] => DT5
                                                            [instituteNumber] => Array
                                                                (
                                                                )
                                                        )
                                                )
                                        )
                                )
                        )
                )
        )
)

需求是提取Personeel分组下所有子分组的[name]和[type]字段数据，示例输出：

[name] => DT
[type] => G

解决方案 #

可以通过遍历定位目标分组后提取子字段，以下是PHP实现示例：

function extractPersoneelChildren($apiData) {
    $result = [];
    // 遍历顶层子分组，找到Personeel分组
    foreach ($apiData['group']['children']['group'] as $group) {
        if ($group['name'] !== 'Personeel') continue;
        
        // 提取该分组下所有子分组的name和type
        foreach ($group['children']['group'] as $childGroup) {
            $result[] = [
                'name' => $childGroup['name'],
                'type' => $childGroup['type']
            ];
        }
        // 如果子分组还有更深嵌套层级，可在此添加递归遍历逻辑
    }
    return $result;
}

// 调用函数并输出结果
$extracted = extractPersoneelChildren($yourApiResponse);
foreach ($extracted as $item) {
    echo "[name] => {$item['name']}\n";
    echo "[type] => {$item['type']}\n";
}

说明 #

• 先遍历顶层子分组，精准定位到名称为Personeel的分组
• 直接提取该分组下children节点内所有子分组的name和type字段
• 若存在多层嵌套的子分组，可在遍历子分组时增加递归调用，实现全层级字段提取
