Shortening a URL with preg_replace

[qwikad.com]

What would be the easiest way to shorten a URL with preg_replace? Let's say a URL looks like this:

http:/ /someurl.com/file_1/something_else/new/file_2.html

I want to reduce it to let's say 30 characters:

http:/ /someurl.com/file_1/some...

Thanks!

I think there's a little more to it if you still want the link to work ;)

Actually, no, I don't want it to work. I just want it for a preview and it doesn't matter if it works or not.

In that case, why not use substr() http://ca3.php.net/manual/en/function.substr.php
