Как преобразовать массив такого вида?

[blocks] => Array
        (
            [1] => Array
                (
                    [0] => Array
                        (
                            [id] => 1
                            [position] => 1
                        )

                )

            [2] => Array
                (
                    [0] => Array
                        (
                            [id] => 2
                             [position] => 2
                        )

                    [1] => Array
                        (
                            [id] => 3
                             [position] => 2
                        )
                )
        )

[blocks] => Array
        (   
            [1] => Array
                (   [position] => 1
