PHP将缺失日期添加到数组(stdClass对象)

i have an array with some employee data and i need to fill the gap for missing dates, i tried but i cannot get it to fill in the missing dates

from an search range: eg. FROM 2015-10-25 to 2015-10-26 current result:

   [92] => Array
        (
            [0] => stdClass Object
                (
                    [DT] => 2015-10-26
                    [CheckIn] => Array
                        (
                            [t] => 15:52
                            [label] => success
                        )

                    [CheckOut] => Array
                        (
                            [t] => 19:41
                            [label] => danger
                        )

                    [Hours] => 3.82
                )

    [56] => Array
        (
            [0] => stdClass Object
                (
                    [DT] => 2015-10-25
                    [CheckIn] => Array
                        (
                            [t] => 12:05
                            [label] => danger
                        )

                    [CheckOut] => Array
                        (
                            [t] => 20:09
                            [label] => danger
                        )

                    [Hours] => 8.07
                ),

            [1] => stdClass Object
                (
                    [DT] => 2015-10-26
                    [CheckIn] => Array
                        (
                            [t] => 12:05
                            [label] => danger
                        )

                    [CheckOut] => Array
                        (
                            [t] => 20:09
                            [label] => danger
                        )

                    [Hours] => 8.07
                )

        )

as you can see the first one is missing 25th, i need need an loop to fill in the missing date.

should look like this:

   [92] => Array
        (
            [0] => stdClass Object
                (
                    [DT] => 2015-10-25
                    [CheckIn] => Array
                        (
                            [t] => NCO
                            [label] => danger
                        )

                    [CheckOut] => Array
                        (
                            [t] => NCO
                            [label] => danger
                        )

                    [Hours] => 3.82
                ),
            [1] => stdClass Object
                (
                    [DT] => 2015-10-26
                    [CheckIn] => Array
                        (
                            [t] => 15:52
                            [label] => success
                        )

                    [CheckOut] => Array
                        (
                            [t] => 19:41
                            [label] => danger
                        )

                    [Hours] => 3.82
                )

    [56] => Array
        (
            [0] => stdClass Object
                (
                    [DT] => 2015-10-25
                    [CheckIn] => Array
                        (
                            [t] => 12:05
                            [label] => danger
                        )

                    [CheckOut] => Array
                        (
                            [t] => 20:09
                            [label] => danger
                        )

                    [Hours] => 8.07
                ),

            [1] => stdClass Object
                (
                    [DT] => 2015-10-26
                    [CheckIn] => Array
                        (
                            [t] => 12:05
                            [label] => danger
                        )

                    [CheckOut] => Array
                        (
                            [t] => 20:09
                            [label] => danger
                        )

                    [Hours] => 8.07
                )

        )

current loop, maybe you can help me implement something withing this:

//this is to join each user by their id
    $result = array();
foreach ($r['d'] as $data) {
  $id = $data->badgenumber;
  if (isset($result[$id])) {
     $result[$id][] = $data;
  } else {
     $result[$id] = array($data);
  }
  $date = $data->DT;
}

Thank you.
