URL link select

[phanh]

Hi, everyone. I'm new to PHP. Hope someone give me an advice one this.
if ($user->confirmed == 0) {
$confirmbutton = "<a href=\"user.php?confirmuser=$user->id&sesskey=$USER->sesskey\">" ("confirm") "</a>";
}

I assign the confirmbutton variable the URL link. How can I determine that the URL link has been selected by the user?

Thanks for any advice,

in user.php, check the contents of the $_GET array to see which variables were passed.
