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); "Todd Cary" <todd@aristesoftware.com> wrote in message news:45F6B3F1.6090308@aristesoftware.com... > Chris Boget wrote: >>> I would like to write a filter that takes the text "smith" or >>> "SMith" >>> and returns "Smith"; same for "ralph smith".
