$from = strtotime('2018-10-25');
$to = strtotime('2018-10-30');
for ($i=$from; $i<=$to; $i+=86400)
    {
         $list[] = date('Y-m-d', $i);

    I suspect you are running into the end of daylight savings time, when the clock gets set back an hour. So adding 24 hours worth of seconds on that day leaves you on the same day.

    It's better to adjust time by days for example using the DateTime class:

    $start = new DateTime('2018-10-25');
    $end = new DateTime('2018-10-29');
    while ($start <= $end) {
        $list[] = $start->format('Y-m-d');
        $start->modify('+1 day');
    }
    print_r($list);
    

    Output

    Array
    (
        [0] => 2018-10-25
        [1] => 2018-10-26
        [2] => 2018-10-27
        [3] => 2018-10-28
        [4] => 2018-10-29
    )
