how to get the nested array count with key values seperated in php

This is my array

Array
(
    [2] => Array
        (
            [0] => Array
                (
                    [id] => 2
                    [res_id] => 1
                    [grand_total] => 303.42
                    [time] => 2016-07-28 11:04:38 AM
                    [status] => 0
                )

            [1] => Array
                (
                    [id] => 2
                    [res_id] => 1
                    [grand_total] => 303.42
                    [time] => 2016-07-28 11:04:38 AM
                    [status] => 0
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [id] => 1
                    [res_id] => 1
                    [grand_total] => 303.42
                    [time] => 2016-07-28 11:04:17 AM
                    [status] => 0
                )

            [1] => Array
                (
                    [id] => 1
                    [res_id] => 1
                    [grand_total] => 303.42
                    [time] => 2016-07-28 11:04:17 AM
                    [status] => 0
                )

        )

)

From this I need sub array count i.e., the array having two indexes such as 2 & 1 from this 2 & 1 there are some nested arrays found such as 0 & 1 for each

Here,I need array count as follows

Array
(
    [2] => Array
        (
            [count] = 2
        )

    [1] => Array
        (
            [count] = 2
        )

)

How should I get this..

Someone help me out of this...

Thank you..
