I used
if(!empty($_SERVER['HTTP_CLIENT_IP']))
{
        //check ip from share internet
        $ip = $_SERVER['HTTP_CLIENT_IP'];
    }
else if(!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
        //to check ip is pass from proxy
        $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
    }
else{
        $ip = $_SERVER['REMOTE_ADDR'];
    }
echo  $ip;
to get client ip address
It is working when I test it on my local server but when I upload my files into remote server where i am hosting my web it is fetching my server ip address not client ip
