From: Operating system: CentOS 5.5 x86_64 PHP version: 5.3.2 Package: Date/time related Bug Type: Bug Bug description:strtotime() unexpectedly changed from 5.2.13 to 5.3.2 breaking alot of scripts
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 bug report at http://bugs.php.net/bug.php?id=52143&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52143&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52143&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52143&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52143&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52143&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52143&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52143&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52143&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52143&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52143&r=support Expected behavior: http://bugs.php.net/fix.php?id=52143&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52143&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52143&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52143&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52143&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52143&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52143&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52143&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52143&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52143&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52143&r=mysqlcfg
