PHP如何对json对象id进行分组

$json = '[
    {"id": 1, "name": "John"},
    {"id": 2, "name": "Jane"},
    {"id": 1, "name": "Tom"},
    {"id": 3, "name": "Alice"}
]';

$data = json_decode($json, true);

$groupedData = array_reduce($data, function($carry, $item) {
    $id = $item['id'];
    if (!isset($carry[$id])) {
        $carry[$id] = [];
    }
    $carry[$id][] = $item;
    return $carry;
}, []);

print_r($groupedData);

Array
(
    [1] => Array
        (
            [0] => Array
                (
                    [id] => 1
                    [name] => John
                )

            [1] => Array
                (
                    [id] => 1
                    [name] => Tom
                )

        )

    [2] => Array
        (
            [0] => Array
                (
                    [id] => 2
                    [name] => Jane
                )

        )

    [3] => Array
        (
            [0] => Array
                (
                    [id] => 3
                    [name] => Alice
                )

        )

)
