Yes.
When link.php "does some stuff" have it send a HEAD request to the link
url.
If it comes back as "200 Ok" forward the user to the page, if it comes back
as "404 Not Found" or any other error response show the user an error page
on your site and log the error for that link.
If the response comes back with a 3** redirect, you could parse that url
and check it (possibly set up a loop to check multiple redirects), forward
the user, or just show an error if you don't want the links to redirect
your users.
