<h2>Get Remote IP Address in PHP</h2>
function getRemoteIPAddress() {
$ip = $_SERVER['REMOTE_ADDR'];
return $ip;
}
The above code will not work in case your client is behind proxy server. In that case use below function to get real IP address of client.
function getRealIPAddr()
{
if (!empty($_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;
}
