Here's a simple php function to get the real IP of a client - Utilizing it inside a function so as to avoid duplicate code.
I use this function on most of my projects and have found it very reliable when dealing with getting the users real IP.
Enjoy :)
function GetClientIP()
{
$ClientIPArr = array(
"HTTP_CLIENT_IP",
"HTTP_CF_CONNECTING_IP",
"HTTP_X_FORWARDED",
"HTTP_X_FORWARDED_FOR",
"HTTP_FORWARDED_FOR",
"REMOTE_ADDR"
);
$found = 0;
foreach ($ClientIPArr as $value)
{
if (isset($_SERVER[$value]))
{
if (filter_var($_SERVER[$value], FILTER_VALIDATE_IP)) {
$ClientIP = $_SERVER[$value];
$found++;
break;
}
}
}
if ($found > 0)
{
return $ClientIP;
}
else
{
return 'Not Found';
}
}
echo GetClientIP();
