Find Visitor’s IP address in PHP

04 Sep

Relying on $_SERVER[‘REMOTE_ADDR’] to find your client’s ip address is not always good. Looking for a wide solution?

Then use this function.

function get_ip() {
$ip = '';
if ($_SERVER['HTTP_CLIENT_IP'])
$ip = $_SERVER['HTTP_CLIENT_IP'];
else if($_SERVER['HTTP_X_FORWARDED_FOR'])
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if($_SERVER['HTTP_X_FORWARDED'])
$ip = $_SERVER['HTTP_X_FORWARDED'];
else if($_SERVER['HTTP_FORWARDED_FOR'])
$ip = $_SERVER['HTTP_FORWARDED_FOR'];
else if($_SERVER['HTTP_FORWARDED'])
$ip = $_SERVER['HTTP_FORWARDED'];
else if($_SERVER['REMOTE_ADDR'])
$ip = $_SERVER['REMOTE_ADDR'];
else
$ip = '';

return $ip;
}
