Array
(
     [1] => Array
        (
            [media_id] => 3b9179b13a7943f0818e82ff7970a8ba

        )
    [2] => Array
        (
        [media_id] => e2f440d4a6314027b967f414e6692204

        [duration] => 312733
    )

[3] => Array
    (
        [media_id] => 0fb7fff38ced4dfc8061bf1528902384
        [title] => Eat This: Weinrich's Bakery

        [thumbnail_url] => P_.120x66.jpeg
        [duration] => 274133
    )

[4] => Array
    (
        [media_id] => 76ac830d33f34a7c97c725e341246376

            [duration] => 262633
    )
)

)

Array keys changed 1,2,3,4 from 0,1,2,3,4 I want my array keys start from 0,1,3,4,5, and so on.
