I'm looking for the absolute best way of blocking proxies coming onto my site. The reason is due to me using unique IP address's on my project.

推荐答案

我不知道实现此目的的防弹方法，但这几乎是完整的:

I'm not aware of a bulletproof way to do this, but this would be pretty much complete:

if (get_ip_address() !== get_ip_address(true))
{
    echo 'using proxy';
}

此get_ip_address()函数已被修改

This get_ip_address() function was adapted from this answer and goes as follows:

function get_ip_address($proxy = false)
{
    if ($proxy === true)
    {
        foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED') as $key)
        {
            if (array_key_exists($key, $_SERVER) === true)
            {
                foreach (array_map('trim', explode(',', $_SERVER[$key])) as $ip)
                {
                    if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4 | FILTER_FLAG_IPV6 | FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false)
                    {
                        return $ip;
                    }
                }
            }
        }
    }

    return $_SERVER['REMOTE_ADDR'];
}
