Finding IP of a website that referring to my PHP script

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 !

Alright, so you want, that if someone adds your JS to his website, you should get a notification with the IP of the website owner. — Akshay, Nov 09 '15 at 12:08
I don't think this is possible unless they add something(variable) to the link for you to catch this — davejal, Nov 09 '15 at 12:11
How about [gethostbyname](http://php.net/manual/en/function.gethostbyname.php)? — putvande, Nov 09 '15 at 12:15

You could try looking at the REFERER http header, which should contain the URL of the site, but there is no guarantee that it will give you the correct value.

// First get the referrer
$referer = $_SERVER['HTTP_REFERER'];

// Parse the referer url
$parts = parse_url($referer);

// Then do a NS lookup to get the IP
$ip = gethostbyname($parts['host']);

Just make sure that your are aware of the fact that the REFERER header can be faked. And the NS lookup is not always fast - or correct.

Can I rely on Referer HTTP header?

This doesn't answer the question as the OP is asking how to get the IP address. – putvande Nov 09 '15 at 12:13
Thanks for the comment, @putvande. I have fixed the example code now. – Anders Marzi Tornblad Nov 09 '15 at 12:16
@TomerW Because they are two different things!! – Anders Marzi Tornblad Nov 09 '15 at 14:08

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
