Bug #77969 [NEW]: DateInterval given wrong d/m values if difference has Febuary month
From: michal dot jusiega at gmail dot com
Operating system: Windows
PHP version: 7.2.18
Package: Date/time related
Bug Type: Bug
Bug description:DateInterval given wrong d/m values if difference has Febuary month
Description:
------------
February is usually 28 days and leap 29 days a year. The problem is that
when calling the script, we should get an equal two months instead of
one month and 28 days. The situation also has when we call for 2020,
then we will receive 1 day and 29 days. For the remaining months in
which February does not exist, DateInterval returns the correct result
as the number of months assuming the first day of the month.
The probable errors occurs in all PHP version in 7.1 + what show a
3v4l.org
https://3v4l.org/KeTaO
Test script:
---------------
<?php
$lastDate = new DateTime('2019-03-01');
$firstDate = new DateTime('2019-01-01');
$dateInterval = $lastDate->diff($firstDate);
var_dump($dateInterval);
Expected result:
----------------
object(DateInterval)#3 (16) { ["y"]=> int(0) ["m"]=> int(2)
["d"]=>
int(0) ["h"]=> int(0) ["i"]=> int(0) ["s"]=> int(0)
["f"]=> float(0)
["weekday"]=> int(0) ["weekday_behavior"]=> int(0)
["first_last_day_of"]=> int(0) ["invert"]=> int(1) ["days"]=>
int(59)
["special_type"]=> int(0) ["special_amount"]=> int(0)
["have_weekday_relative"]=> int(0) ["have_special_relative"]=> int(0) }
Actual result:
--------------
object(DateInterval)#3 (16) { ["y"]=> int(0) ["m"]=> int(1)
["d"]=>
int(28) ["h"]=> int(0) ["i"]=> int(0) ["s"]=> int(0)
["f"]=> float(0)
["weekday"]=> int(0) ["weekday_behavior"]=> int(0)
["first_last_day_of"]=> int(0) ["invert"]=> int(1) ["days"]=>
int(59)
["special_type"]=> int(0) ["special_amount"]=> int(0)
["have_weekday_relative"]=> int(0) ["have_special_relative"]=> int(0) }
