如何在共享服务器上配置GeoIP？

I want to configure GeoIP to redirect domain to a subdomains according to country IP address in a shared server. I have created a custom php.ini to import geoip.so then in my index.php I added this code:

<?php
    require_once('/home/fuiba/php.ini');
    $gi = geoip_open('GeoIP.dat', GEOIP_MEMORY_CACHE);
    $country = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);

    geoip_close($gi);
    $my_countries = 'fr';
    if (strtolower($country) == $my_countries) {
        header('Location: fr.fuiba.org');
    }
    $my_countriessss = 'us';
    if (strtolower($country) == $my_countriessss) {
        header('Location: en.fuiba.org');
    }
?>

In the browser I get this error:

extension=geoip.so
Fatal error: Call to undefined function geoip_open() in /home/fuiba/public_html/index.php on line 3

The GeoIP is installed in the Server. I checked it on info.php: geoip version 1.0.8.

You can't include a php.ini with a php script, and you don't need to since phpinfo() return that it's already installed.

What you need to do in order to make GeoLite work is to first include geoip.inc file include("include/geoip.inc");

Here is where you can find it if you don't already have it : https://github.com/maxmind/geoip-api-php/blob/master/src/geoip.inc

<?php
   include("include/geoip.inc");
   $country = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);

    geoip_close($gi);
    $my_countries = 'fr';
    if (strtolower($country) == $my_countries) {
        header('Location: fr.fuiba.org');
    }
    $my_countriessss = 'us';
    if (strtolower($country) == $my_countriessss) {
        header('Location: en.fuiba.org');
    }
?>
