我有一个像这样的数组：

                    [id] => 1234
                    [name] => John
                )

             [1] => Array
                (

                )
        )

    [1] => Array
        (
            [0] => Array
                (
                    [id] => 1234
                    [name] => John
                )

            [1] => Array
                (
                    [id] => 5678
                    [name] => Sally
                )
            [2] => Array
                (
                    [id] => 1234
                    [name] => Duke
