remote_addr PHP

网上很多伪造ip刷票,可是现在的网站获取ip只用$_SERVER["REMOTE_ADDR"],那应该如何去伪造呢?

回复讨论(解决方案)

$_SERVER["REMOTE_ADDR"] 不可伪造!
但你可以通过代理来改变,当然他反映的是代理的IP,也是真实的

php的curl加代理就可以了。
首先你去找一堆代理ip,很容易就能找到上百个。
若是投票每个一小时才能投一次,那么你就可以每一小时投一百次,目前只能这样做了。

不过小心被封,我之前有帮同学弄过一次投票,后来那个展品被封了。。。

第一次听说~~~学习下

学习下,好资料

获取真实的ip 方法
function real_ip()
{
    static $realip = NULL;

    if ($realip !== NULL)
    {
        return $realip;
    }

    if (isset($_SERVER))
    {
        if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
        {
            $arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);

            /* 取X-Forwarded-For中第一个非unknown的有效IP字符串 */
            foreach ($arr AS $ip)
            {
                $ip = trim($ip);

                if ($ip != 'unknown')
                {
                    $realip = $ip;

                    break;
                }
            }
        }
        elseif (isset($_SERVER['HTTP_CLIENT_IP']))
        {
            $realip = $_SERVER['HTTP_CLIENT_IP'];
        }
        else
        {
            if (isset($_SERVER['REMOTE_ADDR']))
            {
                $realip = $_SERVER['REMOTE_ADDR'];
            }
            else
            {
                $realip = '0.0.0.0';
            }
        }

    {
        if (getenv('HTTP_X_FORWARDED_FOR'))
        {
            $realip = getenv('HTTP_X_FORWARDED_FOR');
        }
        elseif (getenv('HTTP_CLIENT_IP'))
        {
            $realip = getenv('HTTP_CLIENT_IP');
        }
        else
        {
            $realip = getenv('REMOTE_ADDR');
        }
    }

    preg_match("/[\d\.]{7,15}/", $realip, $onlineip);
    $realip = !empty($onlineip[0]) ? $onlineip[0] : '0.0.0.0';

    return $realip;
}
