Answer 1

Try this

function ip_details($IPaddress) 
{
    $json       = file_get_contents("http://ipinfo.io/{$IPaddress}");
    $details    = json_decode($json);
    return $details;
}

$IPaddress  =  'Your ip address of user';

$details    =   ip_details("$IPaddress");

//echo $details->city;   
 echo $details->country;  
//echo $details->org;      
//echo $details->hostname;

For getting IP address you can use the function given by you or simply you can use

$_SERVER['REMOTE_ADDR']

to get the IP address of the user use as follow:

$ip =  $_SERVER['REMOTE_ADDR'];   // ip = 8.8.8.8
$country = file_get_contents('http://ipinfo.io/8.8.8.8/country'); // for more info visit [enter link description here][1] 
echo $country;  // output = US | UK | IN as per ip (just one country code)
