从多级数组中查找并从其他数组中获取数组键

function findKey($multiArray, $otherArray) {
    foreach ($multiArray as $key => $value) {
        if (is_array($value)) {
            $result = findKey($value, $otherArray);
            if ($result !== false) {
                return $result;
            }
        } else {
            if (in_array($value, $otherArray)) {
                return array_search($value, $otherArray);
            }
        }
    }
    return false;
}

// 示例用法
$multiArray = array(
    'level1' => array(
        'level2' => array(
            'level3' => 'value'
        )
    )
);

$otherArray = array(
    'value'
);

$result = findKey($multiArray, $otherArray);
if ($result !== false) {
    echo "找到了键：" . $result;
} else {
    echo "未找到键";
}
