数组格式和排序

现在是凌晨3点，我超级累，我不知道如何让这个东西工作。下面的数组是从数据库中返回的，包含了过去7天的页面浏览量、日期和消息等信息:

Array
(
  [0] => Array
    (
        [vws] => 9
        [mss] => 0
        [dt] => 2016-06-27
    )
  [1] => Array
    (
        [vws] => 4
        [mss] => 0
        [dt] => 2016-06-26
    )
  [2] => Array
    (
        [vws] => 1
        [mss] => 0
        [dt] => 2016-06-24
    )
  [3] => Array
    (
        [vws] => 7
        [mss] => 0
        [dt] => 2016-06-23
    )
)

这个数组应该包含数据，即使没有页面浏览量或消息，所以这就是我要找的:

Array
(
  [0] => Array
    (
        [vws] => 0
        [mss] => 0
        [dt] => 2016-06-22
    )
  [1] => Array
    (
        [vws] => 13
        [mss] => 1
        [dt] => 2016-06-23
    )
  [2] => Array
    (
        [vws] => 7
        [mss] => 3
        [dt] => 2016-06-24
    )
  [3] => Array
    (
        [vws] => 45
        [mss] => 10
        [dt] => 2016-06-25
    )
  [4] => Array
    (
        [vws] => 0
        [mss] => 0
        [dt] => 2016-06-26
    )
  [5] => Array
    (
        [vws] => 0
        [mss] => 0
        [dt] => 2016-06-27
    )
  [6] => Array
    (
        [vws] => 5
        [mss] => 1
        [dt] => 2016-06-28
    )
)

如果我没有说清楚，我很抱歉。如果你需要更多信息，我会更新我的问题。提前谢谢你

编辑似乎使用dt值作为键是一个好主意，但我仍然认为通过使用in_array检查dt值可以更容易地实现相同的结果。

感谢@ArtisiticPhoenix，这段代码现在工作得很好:

    $new = [];
    foreach ($data as $k => $v) {
        $new[$v['dt']] = $v;
    }
    $Date = new DateTime();
    $days = [];
    for ($i = 0; $i < 7; ++$i) {
        $days[$Date->format('Y-m-d')] = [
            'vws' => 0,
            'mss' => 0,
            'dt'  => $Date->format('Y-m-d')
        ];
        $Date->modify('-1 days');
    }
    $final = array_merge($days, $new);
