A line of code to implement the anti-theft chain!

The most hope is that the site is collected and hotlinking, today to introduce the anti-theft chain. The ability to implement the anti-theft chain is actually very simple, and here is just one of the ways. Crap not much to say, the code is as follows:

<?php

Header ("Content-type:text/html;charset=utf-8");

Address anti-theft chain issues based on HTTP

$referer = isset ($_server[' http_referer ')? $_server[' http_referer ': ';

if ($referer! = "&& strpos ($referer, ' http://www.nuskinbing.com/') ===0) {

The URL before the jump must be www.nuskinbing.com. If it is not from the site itself, then reject the output details

echo "<br> member information is as follows:";

echo "<br> ..... What to display on this page ... ";

echo "<br>, ......";.. ";"; ";"

}else{

The URL before the jump is not on this site

Header (' location:warning.php ');

}
