php script to show where a visitor comes from

I am looking for a php script that shows where a visitor comes from. lets say Visitor A comes to my webpage via a link on domain.com

The script will be able to show on the webpage "domain.com" using the echo function.

I tried this:
$_SERVER['HTTP_REFERER'];

but all it shows is the URL of my own webpage instead of the referring webpage.

 

do you have a link that you are coming from or are you just typing in domain.com? that might be the problem...lol

 

duh. I DO have a link I am coming from. I placed a link on another of my website to test it. heres the full php code:

<?php
$referer = $_SERVER["HTTP_REFERER"];
$ipaddress = $_SERVER['REMOTE_ADDR'];	//  Requestor IP addr
$request_uri = ltrim($_SERVER['REQUEST_URI'],'/');

if ($_SERVER["HTTP_REFERER"]) {
$parsed = @parse_url(strtolower($referer));
	if ($parsed[host] && !eregi(strtolower("domain.com"),$parsed[host])) {
	echo '<a href="http://';
	echo str_replace("statistics.","www.",str_replace("stats.","www.",$parsed[host]));
	echo '/">';
	echo ucfirst(str_replace("statistics.","",str_replace("stats.","",str_replace("www.","",$parsed[host]))))."</a>";
	}
}
?>

PHP:

 

you can use javascript if you want, just check the

document.referrer

Code (markup):

 

yeah, thats the good alternative, but I do not want to use it unless it is the only choice. I wanted a solution that can output to HTML (php) so that ppl cannot view the code I used. Javascript can be seen in View Source which is not what I want.
