PHP -如何动态输入只知道键的多维数组？

function setNestedValue(array &$array, array $keys, $value) {
    $key = array_shift($keys);
    if (count($keys) === 0) {
        $array[$key] = $value;
    } else {
        if (!isset($array[$key]) || !is_array($array[$key])) {
            $array[$key] = [];
        }
        setNestedValue($array[$key], $keys, $value);
    }
}

// 示例用法
$data = [];
$keys = ['key1', 'key2', 'key3'];
$value = 'Hello World';

setNestedValue($data, $keys, $value);
print_r($data);

Array
(
    [key1] => Array
        (
            [key2] => Array
                (
                    [key3] => Hello World
                )
        )
)

$data = [];
$keys = ['key1', 'key2', 'key3'];
$value = 'Hello World';

$currentArray = &$data;
foreach ($keys as $key) {
    if (!isset($currentArray[$key]) || !is_array($currentArray[$key])) {
        $currentArray[$key] = [];
    }
    $currentArray = &$currentArray[$key];
}

$currentArray = $value;
print_r($data);

Array
(
    [key1] => Array
        (
            [key2] => Array
                (
                    [key3] => Hello World
                )
        )
)
