Bug #72514 [Opn->Ver]: Behaviour of relative date format "this week" has changed

Edit report at https://bugs.php.net/bug.php?id=72514&edit=1 ID: 72514 Updated by: cmb@php.net Reported by: roelharbers at gmail dot com Summary: Behaviour of relative date format "this week" has changed -Status: Open +Status: Verified Type: Bug Package: Date/time related Operating System: Ubuntu, OSX PHP Version: 5.6.23 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: Behavioral change confirmed: <https://3v4l.org/R4T5a>. Apparently, this week is a shortcut for Monday this week, and the date extension assumes monday to be the first day of the week. Thus, the behavior before PHP 5.6.23 has to be regarded as a bug, what has been reported as bug #63740, and recently been fixed[1]. Even though this commit added a NEWS entry, this did neither make it into the PHP 5.6.23 NEWS[2] nor the Changelog[3] nor to the NEWS/Changelog of later versions.

In php v5.6.23, it returns the previous monday. It might be that the new behaviour is better, however, I find no mention of this backward compatibility breaking change in the changelog. Test script: --------------- for v in 5.6.22 5.6.23; do ( echo $v: ; docker run --rm php:$v php -r 'date_default_timezone_set("UTC");echo (new DateTime("2016-06-19"))->modify("this week")->format("c")."\n";') done Expected result: ---------------- I expect both versions to return the same. Actual result: -------------- 5.6.22: 2016-06-20T12:00:00+00:00 5.6.23: 2016-06-13T12:00:00+00:00 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72514&edit=1
