Call reference for country in GeoLite2 using PHP

I'm trying to use the free MaxMind GeoLite2 code to be able to determine the country of a specific IP address.

I am using the Composer-free method that was posted here: Get a localized name of the users city via Maxmind GeoLite2 Free

I'm sure its incredibly simple, but I can't figure out how to actually pass an IP address and have it return the country.

After the $reader = new Reader... line I have $place = $reader->country('##.###.##.###'); (where the #'s are actual IP address numbers) and it's not working. I tried replacing 'country' with 'city' and that didn't work either. I'm sure its something simple, I'm just not sure what parameters I need to be using to get the country returned.

The error that is shown in the error log is 'PHP Fatal error: Call to undefined method MaxMind\Db\Reader::city() in <<< path to benchmark.php >>>)'

Any ideas/suggestions would be greatly appreciated.

Solution

  • There's no city() or country() functions defined in the files you're including (based on the answer you linked to.) Instead you're supposed to use get() to get the IP geographic information, like so:

    require_once __DIR__ . '/' . 'Db/Reader.php';
require_once __DIR__ . '/' . 'Db/Reader/Decoder.php';
require_once __DIR__ . '/' . 'Db/Reader/InvalidDatabaseException.php';
require_once __DIR__ . '/' . 'Db/Reader/Metadata.php';
require_once __DIR__ . '/' . 'Db/Reader/Util.php';     // new 2014/09
use MaxMind\Db\Reader;
$mmdb= 'GeoLite2-Country.mmdb';
$reader = new Reader( __DIR__  . '/' . $mmdb );
$ipData = $reader->get('##.###.##.###');
echo $ipData['country']['names']['en'];

    Where you replace ##.###.##.### with the IP you want to get info for. Obviously this requires you have all the required code files and GeoLite2-Country.mmdb

    So the complete steps would be:

    1. Download the MaxMind-DB-Reader-php from https://github.com/maxmind/MaxMind-DB-Reader-php
    2. Copy the Db folder found in src/MaxMind to the directory with the file containing the above code.
    3. Download the GeoLite2 Country MaxMind DB from http://dev.maxmind.com/geoip/geoip2/geolite2/
    4. Unzip the downloaded gzip and copy the GeoLite2-Country.mmdb file to the same directory as the file containing the above code.
    5. You should now be able to run the above code! Just make sure you replace ##.###.##.### with a real IP.
