IP Geolocation with MaxMind’s GeoLite2

| 0 comments

IP geolocation is something that’s needed more and more as people publish & trade internationally. Stores want to offer different pricing, currencies, shipping rules to different countries, or provide content in different languages.

Many systems have something already baked in, but working on a project recently I needed to do some simple country-level IP geolocation. My previous iteration had used a third party service, but that slowed things down, and had a tendency to be unreliable – recently going AWOL for a couple of weeks!

There are some free GeoLocation databases provided by MaxMind, but I doubt I’m telling you anything new there, it seems to be fairly well known about. However I’ve never actually used them myself directly, so in I dived.

Firstly I used their public PHP wrapper:

I was able to pull it into my project using Composer really easily, download the database and hook it up simply. Running a geolocation really was as simple as their documentation suggested, I ended up with this in my code:

$reader = new GeoIp2\Database\Reader( GEOIP_DB_PATH );
$record = $reader->country( $this->get_user_ip() );
$country = $record->country->isoCode;

Really nice and simple, and a lot more reliable than my previous solution, and definitely something I’d use again in the future without hesitation.
