GeoIP2 PHP API

Description

This package provides an API for the GeoIP2 [web services] (http://dev.maxmind.com/geoip/geoip2/web-services) and [databases] (http://dev.maxmind.com/geoip/geoip2/downloadable). The API also works with the free GeoLite2 databases.

Install via Composer

Define Your Dependencies

We recommend installing this package with Composer. To do this, add geoip2/geoip2 to your composer.json file. If you don't have a composer.json file, create one in the root directory of your project.

{
    "require": {
        "geoip2/geoip2": "0.6.*"
    }
}

Install Composer

Run in your project root:

curl -s http://getcomposer.org/installer | php

Install Dependencies

Run in your project root:

php composer.phar install

Require Autoloader

You can autoload all dependencies by adding this to your code:

require 'vendor/autoload.php';

Installing via Phar

Although we strongly recommend using Composer, we also provide a phar archive containing all of the dependencies for GeoIP2. Our latest phar archive is available on our releases page.

To use the archive, just require it from your script:

require 'geoip2.phar';

Optional C Extension

The MaxMind DB API includes an optional C extension that you may install to dramatically increase the performance of lookups in GeoIP2 or GeoLite2 databases. To install, please follow the instructions included with that API.

The extension has no effect on web-service lookups.

Database Reader

Usage

To use this API, you must create a new \GeoIp2\Database\Reader object with the path to the database file as the first argument to the constructor. You may then call the method corresponding to the database you are using.

If the lookup succeeds, the method call will return a model class for the record in the database. This model in turn contains multiple container classes for the different parts of the data such as the city in which the IP address is located.

If the record is not found, a \GeoIp2\Exception\AddressNotFoundException is thrown. If the database is invalid or corrupt, a \MaxMind\Db\InvalidDatabaseException will be thrown.

See the API documentation for more details.

Example

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

// This creates the Reader object, which should be reused across
// lookups.
$reader = new Reader('/usr/local/share/GeoIP/GeoIP2-City.mmdb');

// Replace "city" with the appropriate method for your database, e.g.,
// "country".
$record = $reader->city('128.101.101.101');

print($record->country->isoCode . "\n"); // 'US'
print($record->country->name . "\n"); // 'United States'
print($record->country->names['zh-CN'] . "\n"); // '美国'

print($record->mostSpecificSubdivision->name . "\n"); // 'Minnesota'
print($record->mostSpecificSubdivision->isoCode . "\n"); // 'MN'

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

print($record->postal->code . "\n"); // '55455'

print($record->location->latitude . "\n"); // 44.9733
print($record->location->longitude . "\n"); // -93.2323

Web Service Client

Usage

To use this API, you must create a new \GeoIp2\WebService\Client object with your $userId and $licenseKey, then you call the method corresponding to a specific end point, passing it the IP address you want to look up.

If the request succeeds, the method call will return a model class for the end point you called. This model in turn contains multiple record classes, each of which represents part of the data returned by the web service.

If there is an error, a structured exception is thrown.

See the API documentation for more details.

Example

<?php
require_once 'vendor/autoload.php';
use GeoIp2\WebService\Client;

// This creates a Client object that can be reused across requests.
// Replace "42" with your user ID and "license_key" with your license
// key.
$client = new Client(42, 'abcdef123456');

// Replace "city" with the method corresponding to the web service that
// you are using, e.g., "country", "cityIspOrg", "omni".
$record = $client->city('128.101.101.101');

print($record->country->isoCode . "\n"); // 'US'
print($record->country->name . "\n"); // 'United States'
print($record->country->names['zh-CN'] . "\n"); // '美国'

print($record->mostSpecificSubdivision->name . "\n"); // 'Minnesota'
print($record->mostSpecificSubdivision->isoCode . "\n"); // 'MN'

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

print($record->postal->code . "\n"); // '55455'

print($record->location->latitude . "\n"); // 44.9733
print($record->location->longitude . "\n"); // -93.2323

What data is returned?

While many of the end points return the same basic records, the attributes which can be populated vary between end points. In addition, while an end point may offer a particular piece of data, MaxMind does not always have every piece of data for any given IP address.

Because of these factors, it is possible for any end point to return a record where some or all of the attributes are unpopulated.

See the GeoIP2 web service docs for details on what data each end point may return.

The only piece of data which is always returned is the ipAddress attribute in the GeoIp2\Record\Traits record.

Every record class attribute has a corresponding predicate method so you can check to see if the attribute is set.

Integration with GeoNames

GeoNames offers web services and downloadable databases with data on geographical features around the world, including populated places. They offer both free and paid premium data. Each feature is unique identified by a geonameId, which is an integer.

Many of the records returned by the GeoIP2 web services and databases include a geonameId property. This is the ID of a geographical feature (city, region, country, etc.) in the GeoNames database.

Some of the data that MaxMind provides is also sourced from GeoNames. We source things like place names, ISO codes, and other similar data from the GeoNames premium data set.

Reporting data problems

If the problem you find is that an IP address is incorrectly mapped, please submit your correction to MaxMind.

If you find some other sort of mistake, like an incorrect spelling, please check the GeoNames site first. Once you've searched for a place and found it on the GeoNames map view, there are a number of links you can use to correct data ("move", "edit", "alternate names", etc.). Once the correction is part of the GeoNames data set, it will be automatically incorporated into future MaxMind releases.

If you are a paying MaxMind customer and you're not sure where to submit a correction, please contact MaxMind support for help.

Other Support

Please report all issues with this code using the GitHub issue tracker.

If you are having an issue with a MaxMind service that is not specific to the client API, please see our support page.

Requirements

This code requires PHP 5.3 or greater. Older versions of PHP are not supported.

This library works and is tested with HHVM.

This library also relies on the Guzzle HTTP client and the MaxMind DB Reader.
