Use GeoIP in PHP


The modern way to use GeoIP in PHP is to use MaxMind GeoIP2 PHP API. Go to your project root and install it with composer:

composer require geoip2/geoip2:~2.0

You could see this suggestion:

maxmind-db/reader suggests installing ext-bcmath (bcmath or gmp is required for decoding larger integers with the pure PHP decoder)

OK, let's install php-gmp then:

yum install php-gmp

Go to MaxMind website and download their free GeoLite2 City binary database or buy a more accurate commercial version if you're rich badass.

Unpack the acrhive and put GeoLite2-City.mmdb file where you keep things like that. That's it, now you're ready to use GeoIP in PHP:

require_once 'vendor/autoload.php';
use GeoIp2\Database\Reader;

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

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

var_dump($record->location->latitude, $record->location->longitude);

There are more stuff you can get from their PHP GeoIP API which you can read about at their GitHub repository
