You could create a loop which goes to the next day in the $count_only array, from the $start_date and stopping (returning from the function) upon reaching the $end_date.

function number_of_days_between($start_date, $finish_date, $count_only) {
    $count  = 0;
    $start  = new DateTime("@$start_date");
    $end    = new DateTime("@$finish_date");
    $days   = new InfiniteIterator(new ArrayIterator($count_only));
    foreach ($days as $day) {
        $count++;
        $start->modify("next $day");
        if ($start > $end) {
            return $count;
        }
    }
}
