From: wberg at doce dot ufl dot edu Operating system: Linux 2.4.21-alpha-r4 PHP version: 4.3.9 PHP Bug Type: PCRE related Bug description: Preg_Match ignoring word boundaries
Description: ------------ I run PHP 4.3.4 locally on Win XP Pro / ISS 5. The code supplied works flawlessly. On the Linux server, however, which currently runs PHP 4.3.9, it seems to ignore or mess up the \b word boundaries. The same thing happened when the server ran PHP 4.3.3RC1. Upgrading to 4.3.9 didn't help. You can see the code in action, where it produces the wrong results, on the Linux server at: http://www.kuruvinda.com/test.php You can get full PHP info() on this server at: http://www.kuruvinda.com/c.php Reproduce code: --------------- <?php $Pattern = "\b[aàáâäå]rm[eèéêë]\b"; $Blazon = "D'argent, au lion d'azur, armé et lampassé de gueules, (le lion est quelquefois chargé d'une fleur-de-lis d'or, ou d'un écusson d'or à l'aigle éployée de sable)."; print "Pattern: $Pattern<p>Blazon: $Blazon<p>"; # Should return "Found" if (preg_match("/".$Pattern."/i",$Blazon)) { print "Found"; } else { print "Not Found"; } $Blazon = "D'argent, au lion d'azur, armée et lampassé de gueules, (le lion est quelquefois chargé d'une fleur-de-lis d'or, ou d'un écusson d'or à l'aigle éployée de sable)."; print "<p>Pattern: $Pattern<p>Blazon 2: $Blazon<p>"; # Should return "Not Found" if (preg_match("/".$Pattern."/i",$Blazon)) { print "Found"; } else { print "Not Found"; } ?> Expected result: ---------------- The match should find "armé" as a whole word only in $Blazon and not in $Blazon2. Actual result: -------------- The match does not find "armé" as a whole word in $Blazon, but does find it in $Blazon2, although it isn't a whole word there. -- Edit bug report at http://bugs.php.net/?id=30435&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30435&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30435&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30435&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30435&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30435&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30435&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30435&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30435&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30435&r=support Expected behavior: http://bugs.php.net/fix.php?id=30435&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30435&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30435&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30435&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30435&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30435&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30435&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30435&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30435&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30435&r=mysqlcfg
