You should use the function htmlspecialchars().

$refhost = htmlspecialchars($refhost);

But even through you have changed it, you should just see "Array".
That's because of this line:

> $refhost = parse_url($refurl);

Ok, so you wanted to get the host name, instead of just having
$refhost = htmlspecialchars($refhost);

you have to make it this:
$refhost = htmlspecialchars($refhost['scheme'] . '://' .
$refhost['host'] . (isset($refhost['port']) ? $refhost['port'] : ''));
