The file fake_ip.php where curl makes the request:
Code
Copy the code The code is as follows:
< ?php
$ch = curl_init();
$url = "http://localhost/target_ip.php";
$header = array(
'CLIENT-IP:58.68.44.61' ,
'X-FORWARDED-FOR:58.68.44.61',
);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
$page_content = curl_exec($ch);
curl_close($ch);
echo $page_content;
?>
Requested target file target_ip.php:
Copy code The code is as follows:
echo getenv('HTTP_CLIENT_IP');
echo getenv('HTTP_X_FORWARDED_FOR');
echo getenv('REMOTE_ADDR');
?>
Target file target_ip The IP printing order inside is the current IP acquisition order of many open source systems
Visit fake_ip.php and see the result:
58.68.44.61
58.68.44.61

Example
CURL is indeed very powerful and can forge IPs and sources.
1.php requests 2.php.
1.php code:
Copy code The code is as follows:
$ch = curl_init ();
curl_setopt($ch, CURLOPT_URL, "http://localhost/2.php");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.8', 'CLIENT-IP:8.8.8.8')); //Construct IP
curl_setopt($ch, CURLOPT_REFERER, "http://www.jb51.net/ "); //Construct source
curl_setopt( $ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);
2.php code is as follows:
Copy code The code is as follows:
function getClientIp() {
if (!empty($_SERVER["HTTP_CLIENT_IP "]))
$ip = $_SERVER["HTTP_CLIENT_IP"];
else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
else if (!empty($_SERVER["REMOTE_ADDR"]))
$ip = $_SERVER["REMOTE_ADDR"];
else
$ip = "err";
return $ip;
}
echo "IP: " . getClientIp() . "";
echo "referer: " . $_SERVER["HTTP_REFERER"];
fake Success, does this provide a good IP change solution for friends who "fake tickets"
