user ip detection

Question

how to find realy ip adress if use vpn and proxy

Answer 1

You can't... that's why people use VPN & Proxy... ~_~

Answer 2

function getClientIpAddress()
{
//$ipaddress = '';
if (getenv('HTTP_CLIENT_IP'))
$ipaddress = getenv('HTTP_CLIENT_IP');
else if (getenv('HTTP_X_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_X_FORWARDED_FOR');
else if (getenv('HTTP_X_FORWARDED'))
$ipaddress = getenv('HTTP_X_FORWARDED');
else if (getenv('HTTP_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_FORWARDED_FOR');
else if (getenv('HTTP_FORWARDED'))
$ipaddress = getenv('HTTP_FORWARDED');
else if (getenv('REMOTE_ADDR'))
$ipaddress = getenv('REMOTE_ADDR');
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}

Anyway it will no return real ip address if client using proxy, it will return ip of proxy instead.
