[help] readfile and url

I have a PHP file which is loaded with the following on another site:
<? Php read file ("http://abc.com/xxxx.php");?>

Can you write something into the PHP-file(http://abc.com/xxxx.php) which shows the URL of the site where the file is loaded?

I've tried using $_SERVER['PHP_SELF']; but it does not work, I think it's because it is run through the readfile

Any ideas ?

 

well assuming xxxx.php exists within the root/base directory, you can do:

<?php readfile("http://{$_SERVER['HTTP_HOST']}/xxxx.php");?>

PHP:

 

The idea is good. But I can not check if $ _SERVER ['HTTP_HOST'] will be manually changed.
Therefore it's best the feature is located inside the PHP file (http://abc.com/xxxx.php)

 

I've tried using "include", but it does not work across domains

 

Ellaborate? what exactly are you trying to do in more detail? so I can help you better

 

I want to know(track) where this script is loaded <? Php read file ("http://abc.com/xxxx.php");?>

 

You need to enable the "allow_url_include" directive in php.ini. More on it:

http://php.net/manual/en/features.remote-files.php

 

So is http://abc.com/xxxx.php always going to be the same (same domain)?

 

file_get_content is more usefull,but still you should check php.net for help with setting php.ini to remote file inclusion
