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 an IP address
Curl_setopt ($ ch, CURLOPT_REFERER, "http://www.gosoa.com.cn/"); // Construct a path
Curl_setopt ($ ch, CURLOPT_HEADER, 1 );
$ Out = curl_exec ($ ch );
Curl_close ($ ch );

2. the 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"];
