It won't be "hidden", but you can do:
<a href="whatever.php?from=1">1</a>
<a href="whatever.php?from=2">2</a>
<a href="whatever.php?from=3">3</a>
In whatever.php, you'll know which link because of what's in
$_GET['from']:
$from = (int) $_GET['from'];
switch($from){
case 1:
case 2:
case 3:
echo "From link $from<br />\n";
break;
default:
echo "From unknown link: $from<br />\n";
break;
}

Some people have a "gift" link here.
Know what I want?
I want you to buy a CD from some indie artist.
