查找引用我的PHP脚本的网站的IP

Question

I was creating a PHP file that generates a JavaScript code.

In case a website reefers to my code:

<script src="http://myserver.com/myJS.php"></script>

My Question: Is there a way in PHP to find out the WEBSITE's IP that's pointing to my script (Instead of the IP of the visitors of this website) ???

Thanks !

Answer 1

What you need is :

$referer = $_SERVER['HTTP_REFERER']

then do:

$parse   = parse_url($referer);
$host    = $parse['host'];

To get IP:

$ip      = gethostbyname($host);

The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted. SOURCE
