Find referer to my forum

I want to find out what site a visitor has came from to my forum? Is there some php code I could add to my forum home template to get this information? I guess stored in a log file or something.:confused:

Give this a try:
<?
$ref = $_SERVER['HTTP_REFERER'];
$ref = explode("/", $ref);

echo $ref[2];
?>
If using the $_SERVER variable, you can get the website that the visitor came from. It should help you to know which website is referring visitors to you! :D
