PHP curl偽造IP地址和header信息代碼實例

    這篇文章主要介紹了PHP curl偽造IP地址和header信息代碼實例,本文給出服務器端和客戶端實現(xiàn)代碼,提供偽造功能和服務器端檢測代碼,需要的朋友可以參考下
    curl雖然功能強大，但是只能偽造$_SERVER["HTTP_X_FORWARDED_FOR"]，對于大多數(shù)IP地址檢測程序來說，$_SERVER["REMOTE_ADDR"]很難被偽造：
    首先是client.php的代碼
    代碼如下:
    $headers['CLIENT-IP'] = '202.103.229.40';
    $headers['X-FORWARDED-FOR'] = '202.103.229.40';
    $headerArr = array();
    foreach( $headers as $n => $v ) {
    $headerArr[] = $n .':' . $v;
    }
    ob_start();
    $ch = curl_init();
    curl_setopt ($ch, CURLOPT_URL, "");
    curl_setopt ($ch, CURLOPT_HTTPHEADER , $headerArr ); //構造IP
    curl_setopt ($ch, CURLOPT_REFERER, ""); //構造來路
    curl_setopt( $ch, CURLOPT_HEADER, 1);
    curl_exec($ch);
    curl_close ($ch);
    $out = ob_get_contents();
    ob_clean();
    echo $out;
    然后是server.php
    代碼如下:
    function GetIP(){
    if(!emptyempty($_SERVER["HTTP_CLIENT_IP"]))
    $cip = $_SERVER["HTTP_CLIENT_IP"];
    else if(!emptyempty($_SERVER["HTTP_X_FORWARDED_FOR"]))
    $cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
    else if(!emptyempty($_SERVER["REMOTE_ADDR"]))
    $cip = $_SERVER["REMOTE_ADDR"];
    else
    $cip = "無法獲取!";
    return $cip;
    }
    echo "
    訪問IP: ".GetIP()."
    ";
    echo "
    訪問來路: ".$_SERVER["HTTP_REFERER"];
