Php如果日期不连续，则将天数添加到数组

Question

我有一个日期可以是非连续的数组

$dates = 
    Array ( [0] => 17-06-2017 [1] => 18-06-2017 [2] => 22-06-2017 [3] => 23-06-2017 [4] => 24-06-2017 [5] => 30-06-2017 [6] => 09-07-2017 [7] => 10-07-2017 [8] => 11-07-2017 [9] => 12-07-2017 [10] => 13-07-2017 )

如果天数不连续且间隔小于8天，请添加缺失的范围

这是添加到数组

的日期

19-06-2017 20-06-2017 21-06-2017 25-06-2017 26-06-2017 27-06-2017 28-06-2017 29-06-2017 

从 01-07-2017 到 08-07-2017 的时间间隔为no，因为大于8天

如果间隔小于8天，则创建范围$ date_from，$ date_to

$arrayRanges = $this->createDateRangeArray($date_from, $date_to);
foreach ($arrayRanges as $key => $arrayRange) {
   array_push($dates, date('Y-m-d', strtotime($arrayRange)));
}

public function createDateRangeArray($strDateFrom,$strDateTo) {
        $aryRange=array();
        $iDateFrom=mktime(1,0,0,substr($strDateFrom,5,2),substr($strDateFrom,8,2),substr($strDateFrom,0,4));
        $iDateTo=mktime(1,0,0,substr($strDateTo,5,2),substr($strDateTo,8,2),substr($strDateTo,0,4));

        if ($iDateTo>=$iDateFrom) 
        {
           array_push($aryRange,date('d-m-Y',$iDateFrom)); // first entry

           while ($iDateFrom<$iDateTo) 
           {
           $iDateFrom+=86400; // add 24 hours
           array_push($aryRange,date('d-m-Y',$iDateFrom));
           }
         }
           return $aryRange;
    }
