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"
