MaxMind GeoIP Legacy PHP API
Important Note
This API is for the GeoIP Legacy format (dat). To read the MaxMind DB format
(mmdb) used by GeoIP2, please see
our GeoIP2 PHP API.
Requirements
This module has no external dependencies. You only need a MaxMind GeoIP
database.
Install via Composer
We recommend installing this package with Composer.
Download Composer
To download Composer, run in the root directory of your project:
curl -sS https://getcomposer.org/installer, php
You should now have the file composer.phar in your project directory.
Install Dependencies
Run in your project root:
php composer.phar require geoip/geoip:~1.16
You should now have the files composer.json and composer.lock as well as
the directory vendor in your project directory. If you use a version control
system, composer.json should be added to it.
Require Autoloader
After installing the dependencies, you need to require the Composer autoloader
from your code:
require 'vendor/autoload.php';
Install without Composer
Place the 'geoip.inc' file in the include_path as specified in your
php.ini file or place it in the same directory as your PHP scripts.
IP Geolocation Usage
IP geolocation is inherently imprecise. Locations are often near the center of
the population. Any location provided by a GeoIP database should not be used to
identify a particular address or household.
Usage
Gets country name by hostname :
<?php
require 'vendor/autoload.php';
$gi = geoip_open("/usr/local/share/GeoIP/GeoIP.dat",GEOIP_STANDARD);
echo geoip_country_code_by_addr($gi, "24.24.24.24") . "\t" .
geoip_country_name_by_addr($gi, "24.24.24.24") . "\n";
echo geoip_country_code_by_addr($gi, "80.24.24.24") . "\t" .
geoip_country_name_by_addr($gi, "80.24.24.24") . "\n";
geoip_close($gi);
Memory Caching
To enable memory caching, pass GEOIP_SHARED_MEMORY or GEOIP_MEMORY_CACHE
as the second argument of geoip_open.
GEOIP_SHARED_MEMORY requires php >= 4.0.4 compiled with --enable-shmop
configure time. See (http://us2.php.net/manual/en/ref.shmop.php).
In addition, you should call geoip_load_shared_mem before calling
geoip_open. See sample_city.php for an example of shared memory caching.
Requirements
This code is tested on PHP 5.4 and greater. Older versions of PHP may work.
