From: glen at delfi dot ee Operating system: PLD Linux PHP version: 5.2.9 PHP Bug Type: Feature/Change Request Bug description: mktime should return -1 or false on invalid args, but returns 943912800
Description: ------------ http://php.net/mktime "mktime() returns the Unix timestamp of the arguments given. If the arguments are invalid, the function returns FALSE (before PHP 5.1 it returned -1)." but it returns "Tue Nov 30 00:00:00 1999 +0200" instead when invalid input like null (or undefined) is used: php -r 'echo mktime(0, 0, 0, null, null, null), "\n";' 943912800 ok, i understand if all params are 0, then it would make sense: "The number of the year, may be a two or four digit value, with values between 0-69 mapping to 2000-2069 and 70-100 to 1970-2000. On systems where time_t is a 32bit signed integer, as most common today, the valid range for year is somewhere between 1901 and 2038. However, before PHP 5.1.0 this range was limited from 1970 to 2038 on some systems (e.g. Windows)." Year as 0 is 2000, Month 0 is calculated as 12 of the last year, thus it gets December and 0 December is 30 November please make using undefined variables and nulls being invalid input (so that you must cast to int, to treat empty input as 0): php -r 'echo mktime(0, 0, 0, (int )$_GET['day'], (int )$_GET['month'], (int )$_GET['year']), "\n";' -- Edit bug report at http://bugs.php.net/?id=47806&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47806&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47806&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47806&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47806&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47806&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47806&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47806&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47806&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47806&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47806&r=support Expected behavior: http://bugs.php.net/fix.php?id=47806&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47806&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47806&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47806&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47806&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47806&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47806&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47806&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47806&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47806&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47806&r=mysqlcfg
