phpcurl伪造ip的简单例子

3. $ch = curl_init();
4. curl_setopt($ch, CURLOPT_URL, "http://localhost/index.php");
5. $r = rand(1,255);
6. curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.'.$r, 'CLIENT-IP:125.8.8.'.$r)); //构造IP
7. curl_setopt($ch, CURLOPT_REFERER, "http://bbs.it-home.org"); //构造来路
8. curl_setopt($ch, CURLOPT_HEADER, 0); // 0 不输出 ， 1 输出
9. $out = curl_exec($ch);
10. curl_close($ch);
11. ?>

2，php伪造ip地址信息 index.php

2. function getClientIp() {
3. if (!empty($_SERVER["HTTP_CLIENT_IP"]))
4. $ip = $_SERVER["HTTP_CLIENT_IP"];
5. else if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"]))
6. $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
7. else if (!empty($_SERVER["REMOTE_ADDR"]))
8. $ip = $_SERVER["REMOTE_ADDR"];
9. else
10. $ip = "err";
11. return $ip;
12. }
13. echo "IP: " . getClientIp() . "";
14. //echo "referer: " . $_SERVER["HTTP_REFERER"];
15. ?>
