# create DateTime object with time at 00:00:00
$from = new DateTime('today');
# create DateTime object from ymd format
# format character ! resets all fields (year, month, ...) to the Unix Epoch and then sets the inputed date
$to = DateTime::createFromFormat('!ymd', '141118');
# calculate difference between $from and $to and return DateInterval object
$diff = $from->diff($to);
# echo difference of total number of days
