Moving an array key to the top

I have a set of array:

{
    "comments": [
        {
            "user_id": "44",
            "comment": "what"
        }
    ],
    "item_id": "3"
}

Is it possible to move "item_id" key to the above "comments" array?

Here is my code in php: https://www.refheap.com/21279

fuck off

$response_arr = array('item_id' => $response_arr['item_id']) + $response_arr;

This should handle it... But you should probably be asking yourself why you are doing something which makes the ordering of elements in an associative array important.
