Bug description: preg_match backslash-w matches digits
Description:
------------
In a pattern parsed by preg_match, the 'backslash-w' meta-character (which
is described as matches 'any "word" character') matches digits as well
(i.e. [0-9]). This is true inside and outside of square-brackets.
Reproduce code:
---------------
$subject = "12345";
$result = preg_match('/\w+/i', $subject);
echo "\w result: $result <br />";
$result = preg_match('/[a-z]+/i', $subject);
echo "[a-z] result: $result <br />";
Expected result:
----------------
\w result: 0
[a-z] result: 0
Actual result:
--------------
\w result: 1
[a-z] result: 0
