Re: Capitalizing the first letter

For your filter to return only/no digits, I would recommend doing a bit of 
reading on preg_replace ( http://us2.php.net/preg_replace ) while noting the 
following flags:

\d
Matches any decimal digit; this is equivalent to the class [0-9].

\D
Matches any non-digit character; this is equivalent to the class [^0-9].

ex:
preg_replace('/\d/', '', $str);
preg_replace('/\D/', '', $str);
