From: john at designingforbusiness dot com Operating system: OS X, Ubantu PHP version: 5.2.8 PHP Bug Type: *General Issues Bug description: mktime returns the wrong number of days for November. Description: ------------ While using date("d", mktime(0,0,0,11+1,0,2008); to retrieve the number of days in November I continually have 29 returned. While December and other months are correct. Reproduce code: --------------- foreach($this->vacationDays as $entry) { $nowdate = split("/", $entry[1]); $ourDate = mktime(0,0,0,(int)$nowdate[0],(int)$nowdate[1],(int)$nowdate[2]); $ourMonth = date("M", $ourDate); $ourDay = date("D", $ourDate); $ourYear = date("o", $ourDate); $firstDayOfMonth = mktime(0,0,0, $nowdate[0], 1 , $nowdate[2]); $firstDayInMonth = date("D", $firstDayOfMonth); $daysInMonth = date("d", mktime(0,0,0,(int)($nowdate[0]+1), 0, (int)$nowdate[2])); $day_of_week = $firstDayInMonth; switch($day_of_week) { case "Sun": $blank = 0; break; case "Mon": $blank = 1; break; case "Tue": $blank = 2; break; case "Wed": $blank = 3; break; case "Thu": $blank = 4; break; case "Fri": $blank = 5; break; case "Sat": $blank = 6; break; } if(isset($currentMonth) && $ourMonth != $currentMonth) { $currentMonth = $ourMonth; $this->startCalendarMonth($ourMonth, $ourYear); $day_count = $this->shootBlanks($blank); for($day_num = 1; $day_num <= $daysInMonth; $day_num++) { echo "<td>$day_num</td>"; $day_count++; if($day_count > 7) { echo "</tr>\n <tr>"; $day_count = 1; } } $this->endCalendar(); } Expected result: ---------------- The expected result is that November 2008 would return 30 days and December 2008 return 31 days. Actual result: -------------- The current result is Nov 2008 returns 29 days and December 2008 returns 31. Clearly the problem is with November. -- Edit bug report at http://bugs.php.net/?id=46861&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46861&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46861&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46861&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46861&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46861&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46861&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46861&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46861&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46861&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46861&r=support Expected behavior: http://bugs.php.net/fix.php?id=46861&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46861&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46861&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46861&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46861&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46861&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46861&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46861&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46861&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46861&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46861&r=mysqlcfg
