例子，伪造ip的代码段。
复制代码 代码示例:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://localhost/index.php");
$r = rand(1,255);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:8.8.8.'.$r, 'CLIENT-IP:125.8.8.'.$r)); //构造IP
curl_setopt($ch, CURLOPT_REFERER, "http://www.jb200.com"); //构造来路
curl_setopt($ch, CURLOPT_HEADER, 0); // 0 不输出 ， 1 输出
$out = curl_exec($ch);
curl_close($ch);
?>
2，php伪造IP地址信息 index.php
复制代码 代码示例:
<?php
function getClientIp() {
if (!empty($_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"];
?>
