#30435 [Opn]: Preg_Match ignoring word boundaries

ID: 30435 User updated by: wberg at doce dot ufl dot edu Reported By: wberg at doce dot ufl dot edu Status: Open Bug Type: PCRE related Operating System: Linux 2.4.21-alpha-r4 PHP Version: 4.3.9 New Comment: "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." Should be: The match does not find "armé" as a whole word in Blazon, but does find it in Blazon 2, although it isn't a whole word there.

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 this bug report at http://bugs.php.net/?id=30435&edit=1
