From: Operating system: Linux & Darwin PHP version: 5.3.8 Package: Date/time related Bug Type: Bug Bug description:strtotime() returns erroneous result on nonsense DATE_RSS format date strings
Description: ------------ (Note: I was only able to test on 5.2.16, 5.3.0, and 5.3.4. Since there is no evidence of it being fixed in the changelog of 5.3.8, I assume it's still there.) The ninth of May, 2010, was a Sunday. However, if you assert to strtotime() that it was a Monday, it will return the Unix timestamp for Monday, May 10th. Likewise if you assert the ninth was a Tuesday, it will return the timestamp for the 11th; a Wednesday the 12th, and so on right up to returning a Unix timestamp for Saturday, 15 May 2010 if you provide it with "Saturday, 9 May 2010". Presumably, the correct behavior is one of (1) to throw an error given a self- contradictory date, (2) to return nothing at all, or (3) to ignore the day-of-the- week element and return the Unix timestamp for the date specified (e.g. 9 May 2010). Returning the timestamp for another date altogether is wrong. Test script: --------------- $datestring="9 May 2010 04:24:36 GMT"; print "\"\": ".strtotime($datestring)." ".date($dateformat, strtotime($datestri\ ng)) ."\n"; $datestring="Sun, 9 May 2010 04:24:36 GMT"; print "Sun: ".strtotime($datestring)." ".date($dateformat, strtotime($datestrin\ g)) ."\n"; $datestring="Mon, 9 May 2010 04:24:36 GMT"; print "Mon: ".strtotime($datestring)." ".date($dateformat, strtotime($datestrin\ g)) ."\n"; $datestring="Tue, 9 May 2010 04:24:36 GMT"; print "Tue: ".strtotime($datestring)." ".date($dateformat, strtotime($datestrin\ g)) ."\n"; Expected result: ---------------- "": 1273379076 Sun, 09 May 2010 00:24:36 -0400 Sun: 1273379076 Sun, 09 May 2010 00:24:36 -0400 Mon: 1273379076 Sun, 09 May 2010 00:24:36 -0400 Tue: 1273379076 Sun, 09 May 2010 00:24:36 -0400 (Alternatively: "": 1273379076 Sun, 09 May 2010 00:24:36 -0400 Sun: 1273379076 Sun, 09 May 2010 00:24:36 -0400 Mon: Tue: ) Actual result: -------------- "": 1273379076 Sun, 09 May 2010 00:24:36 -0400 Sun: 1273379076 Sun, 09 May 2010 00:24:36 -0400 Mon: 1273465476 Mon, 10 May 2010 00:24:36 -0400 Tue: 1273551876 Tue, 11 May 2010 00:24:36 -0400 -- Edit bug report at https://bugs.php.net/bug.php?id=55575&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55575&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55575&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55575&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55575&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55575&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55575&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55575&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55575&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55575&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55575&r=support Expected behavior: https://bugs.php.net/fix.php?id=55575&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55575&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55575&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55575&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55575&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55575&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55575&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55575&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55575&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55575&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55575&r=mysqlcfg
