PHP: Group array to unique value

Existing array:

Array
(
    [0] => Array
        (
            [id] => 12
            [name] => John
            [description] => this is a description.
        )

    [1] => Array
        (
            [id] => 57
            [name] => John
            [description] => test description.
        )

    [2] => Array
        (
            [id] => 85
            [name] => Amy
            [description] => testing 123.
        )

)

Apply this:

$result = array();

foreach ($arr as $data) {

        $name = $data['name'];
        if (isset($result[$name])) {
                $result[$name][] = $data;
        } else {
                $result[$name] = array($data);
        }

}

Output:

Array
(
        [John] => Array
        (
                [0] => Array
                (
                        [id] => 12
                        [name] => John
                        [description] => this is a description.
                )

                [1] => Array
                (
                        [id] => 57
                        [name] => John
                        [description] => test description.
                )
        )
        [Amy] => Array
        (
                [0] => Array
                (
                        [id] => 85
                        [name] => Amy
                        [description] => testing 123.
                )
        )
)
