Find Referring Domain (without www and any other sub domain) instead of Full path URL

Hello,
I know that the following code prints output of the referring URL.

<?php
$ref=$_SERVER['HTTP_REFERER'];
echo "$ref"; 
?>

Code (markup):

For example the referring URL is http://forums.digitalpoint.com/showthread.php?t=123, i need the value to be grabbed as just digitalpoint removing all the stuff after and before.

The following links may be useful in reaching the solution for this.

PHP str_replace and other PHP Standard functions. I am trying to get this working by preg_replace and str_replace but really couldn't get it working.

Expecting a quick reply from someone who had achieved such a thing.

 

This'll work:

<?

if (isset($_SERVER['HTTP_REFERER'])) { // check there was a referrer

	$uri = parse_url($_SERVER['HTTP_REFERER']); // use the parse_url() function to create an array containing information about the domain
	Echo $uri['host']; // echo the host

}

?>

AimHigher is correct... this will work as you want it to be...

 

Thanks for this. I tried this but I just need something more.

say for example, the referring domain may be

domain.com or www.domain.com

I would like the answer to be domain.com irrespective of that.

So is it possible to match and split ?

 

<?

if (isset($_SERVER['HTTP_REFERER'])) {

	$uri = parse_url($_SERVER['HTTP_REFERER']);
	$domain = substr($uri['host'], strpos($uri['host'], ".")+1, strlen($uri['host']));
	Echo $domain;

}

?>

Code (markup):

If the referrer is something like subdomain.domain.com it will strip the subdomain though.

Here's what you could do if you want to strip www. but keep the subdomains:

<?

if (isset($_SERVER['HTTP_REFERER'])) {

	$uri = parse_url($_SERVER['HTTP_REFERER']);
	$domain = str_replace("www.", "", strtolower($uri['host']));
	Echo $domain;

}

?>
