I thing this function is also a good soloution for get user real IP address if any user used multi IP or Proxy.
function getrealip()
{
if (isset($_SERVER)){
if(isset($_SERVER["HTTP_X_FORWARDED_FOR"])){
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
if(strpos($ip,",")){
$exp_ip = explode(",",$ip);
$ip = $exp_ip[0];
}
}else if(isset($_SERVER["HTTP_CLIENT_IP"])){
$ip = $_SERVER["HTTP_CLIENT_IP"];
}else{
$ip = $_SERVER["REMOTE_ADDR"];
}
}else{
if(getenv('HTTP_X_FORWARDED_FOR')){
$ip = getenv('HTTP_X_FORWARDED_FOR');
if(strpos($ip,",")){
$exp_ip=explode(",",$ip);
$ip = $exp_ip[0];
}
}else if(getenv('HTTP_CLIENT_IP')){
$ip = getenv('HTTP_CLIENT_IP');
}else {
$ip = getenv('REMOTE_ADDR');
}
}
return $ip;
}
