Regex - Web URL

[Kudose]

Hello all. I am try to allow a URL to pass with or without a trailing slash. Then if the URL does not contain a trailing slash, add one. I am having problems with this regex. I thought I was doing so well this evening writting them with no errors, then poof. One I cant seem to figure out. COuld someone please help me on this?

TIA.

$web_url = "www.spechal.com/v4";
if(!eregi("^(www\.)?(.*)+[\.A-Za-z]+[\/]*$", $web_url))
     $err[] = "Error: Web URL is in an invalid format. (www.spechal.com)";
if(!preg_match("#\/#", $web_url))
     $web_url .= '/';

Is the url parsing ok? Is it just the adding final slash the bit that's bad? If so then change your pattern to '#/$#'

But you could just check with substring like, ummm

if (substr($web_url, -1, 1) != '/') $web_url .= '/';

I'm just guessing at the parameter order to substr, but think it's probably alright
