PHP uses CURL to forge IP and source

1.php 请求 2.php 。


1.php代码：

$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'));  //构造IP

curl_setopt($ch, CURLOPT_REFERER, "http://www.gosoa.com.cn/ ");   //构造来路

curl_setopt($ch, CURLOPT_HEADER, 1);

$out = curl_exec($ch);

curl_close($ch);


2.php代码如下：

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"];

The above introduces PHP's use of CURL to forge IP and sources, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
