Maxmind GeoIP2 tutorial (How-to)?

问题

I used GeoIp, with pure PHP codes.. but GeoIp2 become namespaced and etc, and at this moment i couldnt find out how to use that.. i have downloaded GeoLite2-Country.mmdb, and now how to get the country name for IP, i.e. 123.123.123.123.

p.s. I dont have GIT/COMPOSER or etc..

How i did it: let's say, create a folder named "My_Folder" and inside it:

1) create folder GeoIp2 and put in it content of this "SRC" folder (download).
2) put MaxMind folder (download, from "SRC" folder).
3) place i.e. GeoLite2-Country.mmdb (download).

then, in My_Folder create a example.php file and put this code:

$user_ip='123.123.123.123';

spl_autoload_register('func888'); function func888($class){ include_once(str_replace(array('/','\\'), DIRECTORY_SEPARATOR, dirname(__file__)."/$class.php")) ;}
use GeoIp2\Database\Reader; 
//you can do it for "city" too.. just everywhere change phrase "country" with "city".
try{
    $reader = new Reader(dirname(__file__)."/GeoLite2-Country.mmdb");
    $record = $reader->country($user_ip);
    $reader->close();
    $country_name =  $record->raw['country']['names']['en'];
} catch ( GeoIp2\Exception\AddressNotFoundException $e ){    $country_name = 'not_found';  }

echo $country_name;
// RESULTS -------------- > China
