With GeoIP2, the easiest way is to:

​

* Grab the latest GeoIP2 Lite Database(s): https://dev.maxmind.com/geoip/geoip2/geolite2/

* Grab the latest geoip2.phar: https://github.com/maxmind/GeoIP2-php/releases

​

<?php

require_once("geoip2.phar");

use GeoIp2\Database\Reader;

// City DB

$reader = new Reader('/path/to/GeoLite2-City.mmdb');

$record = $reader->city($_SERVER['REMOTE_ADDR']);

// or for Country DB

// $reader = new Reader('/path/to/GeoLite2-Country.mmdb');

// $record = $reader->country($_SERVER['REMOTE_ADDR']);

print($record->country->isoCode . "\n");

print($record->country->name . "\n");

print($record->country->names['zh-CN'] . "\n");

print($record->mostSpecificSubdivision->name . "\n");

print($record->mostSpecificSubdivision->isoCode . "\n");

print($record->city->name . "\n");

print($record->postal->code . "\n");

print($record->location->latitude . "\n");

print($record->location->longitude . "\n");
