Get domain name without port using HTTP_HOST

Question

When I check the logs there are a few rare occasions where for some visitors(bot I think) the $_SERVER['HTTP_HOST'] is returning: www.domain.co.uk:80

What is the correct way to get only the domain name without any ports?

Should I be doing it this way instead:

$url_components = parse_url($_SERVER['HTTP_HOST']);
$domain = $url_components['host'];

The strange thing is that I cant replicate this behavior it only appears in the logs.

Answer 1

In this case $_SERVER['SERVER_NAME'] is your friend.
