This is the error message:

Notice: Undefined index: HTTP_HOST in line 7

here's the line 7 from my code:

if ($_SERVER ['HTTP_HOST'] !== 'localhost') {
exit;
}

if ($_SERVER ['HTTP_HOST'] !== '127.0.0.1') {
exit;
}

It's referencing the $SERVER array.

PHP Manual::Variables::Predefined Variables::$_SERVER wrote:

'HTTP_HOST'
Contents of the Host: header from the current request, if there is one.

If the HTTP_HOST header isn't set, then the $_SERVER array will lack the key (or index) HTTP_HOST, which is why you get the error.

What are you trying to do?
