ID: 52143 Updated by: fel...@php.net Reported by: jason dot woods at blueyonder dot co dot uk Summary: strtotime() unexpectedly changed from 5.2.13 to 5.3.2 breaking alot of scripts -Status: Open +Status: Assigned Type: Bug Package: Date/time related Operating System: CentOS 5.5 x86_64 PHP Version: 5.3.2 -Assigned To: +Assigned To: derick Block user comment: N Previous Comments: ------------------------------------------------------------------------ [2010-06-22 13:01:38] jason dot woods at blueyonder dot co dot uk Description: ------------ In version 5.2.13 the following code: <?php echo ($now = strtotime('+1 day')) . ' - ' . date('d-m-Y H.i.s', $now) . "\n"; echo ($last = strtotime('last week', $now)) . ' - ' . date('d-m-Y H.i.s', $last) . "\n"; echo ($next = strtotime('+1 week', $last)) . ' - ' . date('d-m-Y H.i.s', $next) . "\n"; ?> Gives the following result: 1277283067 - 23-06-2010 09.51.07 1276678267 - 16-06-2010 09.51.07 1277283067 - 23-06-2010 09.51.07 That is, first line is current time. Second time is "last week", otherwise known as "-1 week". Third time is "+1 week", which reverses the change that the "-1 week" did. However, this changed in 5.3.2 and it now gives the following result: 1277281904 - 23-06-2010 09.31.44 1276504304 - 14-06-2010 09.31.44 1277109104 - 21-06-2010 09.31.44 So it appears "last week" is no longer the equivalent of "-1 week". Is this a deliberate change or something that was broken in 5.3.2? I have been unable to test other versions and can only give you the difference from 5.2.13 and 5.3.2. Thanks. Test script: --------------- <?php echo ($now = strtotime('+1 day')) . ' - ' . date('d-m-Y H.i.s', $now) . "\n"; echo ($last = strtotime('last week', $now)) . ' - ' . date('d-m-Y H.i.s', $last) . "\n"; echo ($next = strtotime('+1 week', $last)) . ' - ' . date('d-m-Y H.i.s', $next) . "\n"; ?> Expected result: ---------------- 1277283067 - 23-06-2010 09.51.07 1276678267 - 16-06-2010 09.51.07 1277283067 - 23-06-2010 09.51.07 Actual result: -------------- 1277281904 - 23-06-2010 09.31.44 1276504304 - 14-06-2010 09.31.44 1277109104 - 21-06-2010 09.31.44 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52143&edit=1
