[Nangikaze recommendation] CURL fake IP and source_PHP tutorial

It provides a good IP-changing solution for friends who are "faking votes". After checking, CURL is indeed very powerful and can forge IPs and sources.

1.php requests 2.php.

1.php code:

$ch = curl_init();
curl_setopt($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.gosoa.com.cn/ “); //Construction origin
curl_setopt($ch, CURLOPT_HEADER, 1);
$out = curl_exec($ch);
curl_close($ch);

2.php 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"];

The forgery was successful, isn’t it! !
