Iterating Carbon date inside loop

In my Laravel project I want to create a array of next 7 days dynamically. I have following setup:

    $pickup_dates = [];
    $today = Carbon::today();
    for ($i = 0; $i < 7; $i++) {
      $pickup_dates[] = $today->addDay();
    }
    dd($pickup_dates);

But when I use dd to dump data my output as follows:

Array
(
[0] => Carbon\Carbon Object
    (
        [date] => 2017-08-09 00:00:00.000000
        [timezone_type] => 3
        [timezone] => UTC
    )

[1] => Carbon\Carbon Object
    (
        [date] => 2017-08-09 00:00:00.000000
        [timezone_type] => 3
        [timezone] => UTC
    )

[2] => Carbon\Carbon Object
    (
        [date] => 2017-08-09 00:00:00.000000
        [timezone_type] => 3
        [timezone] => UTC
    )

[3] => Carbon\Carbon Object
    (
        [date] => 2017-08-09 00:00:00.000000
        [timezone_type] => 3
        [timezone] => UTC
    )

[4] => Carbon\Carbon Object
    (
        [date] => 2017-08-09 00:00:00.000000
        [timezone_type] => 3
        [timezone] => UTC
    )

[5] => Carbon\Carbon Object
    (
        [date] => 2017-08-09 00:00:00.000000
        [timezone_type] => 3
        [timezone] => UTC
    )

[6] => Carbon\Carbon Object
    (
        [date] => 2017-08-09 00:00:00.000000
        [timezone_type] => 3
        [timezone] => UTC
    )

)

Can you tell me what is the wrong with this code? Or is there any other way to achieve this?
