这里有一种使用Carbon https://github.com/briannesbitt/Carbon:的方法

public function buildDateRangeArray($first, $last)
{
    while ($first <= $last) {
        $dates[] = $first->toDateString();

        $first->addDay();
    }

    return $dates;
}

当然，这可以被调整为不使用碳。传递给函数的$first和$last参数是Carbon实例。

<?
print_r(getDatesFromRange( '2010-10-01', '2010-10-05' ));

function getDatesFromRange($startDate, $endDate)
{
    $return = array($startDate);
    $start = $startDate;
    $i=1;
    if (strtotime($startDate) < strtotime($endDate))
    {
       while (strtotime($start) < strtotime($endDate))
        {
            $start = date('Y-m-d', strtotime($startDate.'+'.$i.' days'));
            $return[] = $start;
            $i++;
        }
    }

    return $return;
}

$report_starting_date=date('2014-09-16');
$report_ending_date=date('2014-09-26');
$report_starting_date1=date('Y-m-d',strtotime($report_starting_date.'-1 day'));
while (strtotime($report_starting_date1)<strtotime($report_ending_date))
{

    $report_starting_date1=date('Y-m-d',strtotime($report_starting_date1.'+1 day'));
    $dates[]=$report_starting_date1;
  } 
  print_r($dates);

 // dates    ('2014-09-16', '2014-09-26')


 //print result    Array
(
[0] => 2014-09-16
[1] => 2014-09-17
[2] => 2014-09-18
[3] => 2014-09-19
[4] => 2014-09-20
[5] => 2014-09-21
[6] => 2014-09-22
[7] => 2014-09-23
[8] => 2014-09-24
[9] => 2014-09-25
[10] => 2014-09-26
)

这是非常灵活的。
