One thing you could do is resolve the domain name they type in.
Tools like dig or nslookup can do this.

Here's a PHP package (GPL license) that says it does this, but I haven't
used it:

No doubt there are other similar PHP functions available out there.

if ( @open($url, 'r') === FALSE )
echo "URL Fake\n";
else
echo "Go ahead!\n";

That's the one. My mistake -- should have tested it really.

I still advise using the @-sign though:

@fopen()

the @ suppresses PHP's error-printing (assuming you have it switched on at
all), so the visitors won't see any ugly message if things go wrong --
just your own pretty message.
