It rather depends on the webserver but in most cases it will be there. On apache the way it works is when you access the url http://yourhost.com/ The most browsers will send something like: GET / HTTP/1.1 host: yourhost.com The host: header is what HTTP_HOST is. If you can access the site by the IP, I'm not exactly sure what will happen in that case, cause the browser may not send that host: value. With all that said, if you have the HTTP_HOST value, it will most likely be there. php has no control over that var, its set by the webserver.
