From: Operating system: Ubuntu / Mac OSX PHP version: 5.3.8 Package: Date/time related Bug Type: Documentation Problem Bug description:DateTime::setISODate allows weeks to overflow in the next year Description: ------------ This is actually a nice feature for calender data/time operations, but not documented yet: Specifying a week number larger than valid for the year, the end results nicely overflows into the next year. Test script: --------------- <?php echo date( ’W’, strtotime( "December 28th, 2011" ) ), "\n"; $ndate = new DateTime(); $ndate->setISODate(2011,56,07); echo "ndate: " . $ndate->format('Y-m-d') . "\n"; $ndate->setISODate(2012,04,07); echo "ndate: " . $ndate->format('Y-m-d') . "\n"; ?> Expected result: ---------------- 52 ndate: 2012-01-29 ndate: 2012-01-29 Actual result: -------------- 52 ndate: 2012-01-29 ndate: 2012-01-29 -- Edit bug report at https://bugs.php.net/bug.php?id=55799&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55799&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55799&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55799&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55799&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55799&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55799&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55799&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55799&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55799&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55799&r=support Expected behavior: https://bugs.php.net/fix.php?id=55799&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55799&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55799&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55799&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55799&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55799&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55799&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55799&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55799&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55799&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55799&r=mysqlcfg
