detect user ip address using PHP

Question

i have a contact form on my website, and i'm trying to know what is the IP address of the users, i've tried this PHP code on my local testing XAMPP:

function getRealIpAddr()
{
if (!empty($_SERVER['HTTP_CLIENT_IP']))
//check ip from share internet
{
$ip=$_SERVER['HTTP_CLIENT_IP'];
}
 elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
 //to check ip is pass from proxy
  {
    $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
  }
  else
  {
    $ip=$_SERVER['REMOTE_ADDR'];
  }
  return $ip;

}
$ipaddress= getRealIpAddr();

echo "my ip address is" . $ipaddress;

but the results is always like

"my ip address is::1",

I don't know what's wrong with the code.

@AleksG I think it's more a duplicate of this [how to show The IP address in IPv4 which show ::1 in the web page](http://stackoverflow.com/questions/11195688/how-to-show-the-ip-address-in-ipv4-which-show-1-in-the-web-page?rq=1) , however what you posted should be marked as related since there is a lot of useful information in that SO question. — Tim Sanders, Jun 26 '13 at 14:08

That's because you're on your local machine - ::1 is one of the IPv6 addresses of localhost. It's similar to 127.0.0.1. That's because you're accessing your script locally. If you upload this script to a server, and access it via an internet connection, you will be able to see your external IP.

::1 is the same as 127.0.0.1, but in IPv6 notation, so maybe your code is right! Can you check it on a server and compare your results with something like "whatismyip.com" output?
