UBB.Developers Forums UBB.threads 7 Development How Do I? Posting a URL at the end of a sentence

I wouldn't know how to do this in code, but I wonder if this possible.

using http://www.ccc.com. as the example.

if($last_character eq ".") {
$url = $url - $last_character;
}

now I don't have any clue on how to do that in code,but maybe someone will see that and know how

EDIT: changes the link cause I realized my random link went to a porn site
