$dateS = new DateTime('2018-03-01');
$dateE = new DateTime('2018-04-01');
print_r(date_diff($dateS, $dateE));
$dateS = new DateTime('2018-02-01');
$dateE = new DateTime('2018-03-01');
print_r(date_diff($dateS, $dateE));
Expected result:
----------------
DateInterval Object
(
[y] => 0
[m] => 1
[d] => 0
[h] => 0
[i] => 0
[s] => 0
[f] => 0
[weekday] => 0
[weekday_behavior] => 0
[first_last_day_of] => 0
[invert] => 0
[days] => 31
[special_type] => 0
[special_amount] => 0
[have_weekday_relative] => 0
[have_special_relative] => 0
