#46890 [NEW]: Regex works in perl, not with preg_match

From: gohanman at gmail dot com Operating system: CentOS PHP version: 5.2.8 PHP Bug Type: PCRE related Bug description: Regex works in perl, not with preg_match Description: ------------ I'm having a preg_match function fail periodically. I finally found a specific input string that fails in PHP but works fine in Perl. I'm at a loss why. Reproduce code: --------------- $pattern = "/(\w\w\w) (\d+) (\d\d\d\d) (\d+):(\d\d)(\w)M/"; $input = "Dec 17 2008 2:23PM"; $rv = preg_match($pattern, $input, $groups); echo var_dump($rv); Expected result: ---------------- A non-zero result indicating the pattern matched. Actual result: -------------- Zero. -- Edit bug report at http://bugs.php.net/?id=46890&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46890&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46890&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46890&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46890&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=46890&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=46890&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46890&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46890&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46890&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46890&r=support Expected behavior: http://bugs.php.net/fix.php?id=46890&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46890&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46890&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46890&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46890&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46890&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46890&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46890&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46890&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46890&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46890&r=mysqlcfg
