$_SERVER is an array of variables. You are using a blank index which results in the undefined index and variable.
It should look something like $_SERVER['SERVER_NAME'] but without knowing where you want to send the users I cannot direct you much further.
Here is some more info on the $_SERVER variable PHP $_SERVER Sign in to post your reply or Sign up for a free account.

This is as boiled down as I can make it.
