Actually, I was wrong. Using POSIX does *not* work. It won't find
either...

Removing the case insensitivity (i) from the pattern match makes no
difference in the outcome. See:

http://www.kuruvinda.com/test2.php

Using POSIX ereg instead does work. See:

http://www.kuruvinda.com/test3.php

<?php
$Pattern = "[[:<:]][a�����]rm[e����][[:>:]]";

$Blazon = "D'argent, au lion d'azur, arm� et lampass� de gueules, (le
lion est quelquefois charg� d'une fleur-de-lis d'or, ou d'un �cusson
d'or � l'aigle �ploy�e de sable).";

print "Pattern: $Pattern<p>Blazon: $Blazon<p>";

# Should print Found
if (eregi($Pattern,$Blazon,$regs)) {
    print "Found";
} else {
    print "Not Found";
}

$Blazon = "D'argent, au lion d'azur, arm�e et lampass� de gueules, (le
lion est quelquefois charg� d'une fleur-de-lis d'or, ou d'un �cusson
d'or � l'aigle �ploy�e de sable).";

print "<p>Pattern: $Pattern<p>Blazon 2: $Blazon<p>";

# Should print Not Found
if (eregi($Pattern,$Blazon,$regs)) {
    print "Found";
} else {
    print "Not Found";
}
?>

"The match does not find "arm�" 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 "arm�" as a whole word in Blazon, but does find
it in Blazon 2, although it isn't a whole word there.

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

Reproduce code:
---------------
<?php
$Pattern = "\b[a�����]rm[e����]\b";

$Blazon = "D'argent, au lion d'azur, arm� et lampass� de gueules, (le
lion est quelquefois charg� d'une fleur-de-lis d'or, ou d'un �cusson
d'or � l'aigle �ploy�e 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, arm�e et lampass� de gueules, (le
lion est quelquefois charg� d'une fleur-de-lis d'or, ou d'un �cusson
d'or � l'aigle �ploy�e 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 "arm�" as a whole word only in $Blazon and not in
$Blazon2.

Actual result:
--------------
The match does not find "arm�" as a whole word in $Blazon, but does
find it in $Blazon2, although it isn't a whole word there.
