i want to get an ip addres of visitors. could you tell me what element of $_SERVER[] i should use?

$_SERVER['HTTP_CLIENT_IP']; $_SERVER['HTTP_X_FORWARDED_FOR']; or $_SERVER['REMOTE_ADDR']; 

thanks

UPDATE:

If your client is connected to the Internet through Proxy Server then $_SERVER['REMOTE_ADDR'] in PHP just returns the the IP address of the proxy server not of the client’s machine.There are extra Server variable which might be available to determine the exact IP address of the client’s machine in PHP, they are HTTP_CLIENT_IP and HTTP_X_FORWARDED_FOR.
