PHP spoofing IP and source information

Check the next, curl really strong can forge IP and source, the following see realize the need for friends can refer to.

1.php Tutorial Request 2.php.

1.php Code:

$ch = Curl_init ();
curl_setopt ($ch, Curlopt_url, "http://localhost/2.php");
curl_setopt ($ch, Curlopt_httpheader, Array (' x-forwarded-for:8.8.8.8 ', ' client-ip:8.8.8.8 ')); Constructing IP
curl_setopt ($ch, Curlopt_referer, "http://www.111cn.net/"); Structural antecedents
curl_setopt ($ch, Curlopt_header, 1);
$out = curl_exec ($ch);
Curl_close ($ch);
The 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"];
Forgery success, this is not to "brush the ticket" friends to provide a good exchange of IP program!!
