Say I have the following array, how can I sort it on sort_by?

Array
(
    [10] => Array
        (
            [Masthead_slide] => Array
                (
                    [id] => 1456464564
                    [sort_by] => 1
                )

        )

    [6] => Array
        (
            [Masthead_slide] => Array
                (
                    [id] => 645454
                    [sort_by] => 10
                )

        )

    [7] => Array
        (
            [Masthead_slide] => Array
                (
                    [id] => 4547
                    [sort_by] => 5
                )

        )
)
