Bug #74529 [NEW]: DateTime::diff seems to ignore $absolute = true
From: hrovira at seocom dot es
Operating system: Ubuntu 16.04.2 LTS
PHP version: 7.1.4
Package: SPL related
Bug Type: Bug
Bug description:DateTime::diff seems to ignore $absolute = true
Description:
------------
DateTime::diff generates different DateInterval results depending on the
order, even though $absolute param is set to true. date1->diff(date2,
true) is different than date2->diff(date1, true). Please, see test
script.
Test script:
---------------
<?php
$date1 = date_create("2014-11-01 00:00:00");
$date2 = date_create("2017-05-01 04:00:00");
$diff1 = $date2->diff($date1, true);
$diff2 = $date1->diff($date2, true);
echo $diff1->m .' months, '.$diff1->d. ' days';
// outputs: 6 months, 0 days
echo $diff2->m .' months, '.$diff2->d. ' days';
// outputs: 5 months, 30 days
Expected result:
----------------
6 months, 0 days
5 months, 30 days
Actual result:
--------------
6 months, 0 days
6 months, 0 days
