GeoIP2 PHP API
Description
This package provides an API for the GeoIP2
web services and
databases. The API also
works with the free
GeoLite2 databases.
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 geoip2/geoip2:~2.0
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 via Phar
Although we strongly recommend using Composer, we also provide a
phar archive containing most of the
dependencies for GeoIP2. Our latest phar archive is available on
our releases page.
Install Dependencies
In order to use the phar archive, you must have the PHP
Phar extension installed and
enabled.
If you will be making web service requests, you must have the PHP
cURL extension
installed to use this archive. For Debian based distributions, this can
typically be found in the the php-curl package. For other operating
systems, please consult the relevant documentation. After installing the
extension you may need to restart your web server.
If you are missing this extension, you will see errors like the following:
PHP Fatal error: Uncaught Error: Call to undefined function MaxMind\WebService\curl_version()
Require Package
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.
IP Geolocation Usage
IP geolocation is inherently imprecise. Locations are often near the center of
the population. Any location provided by a GeoIP2 database or web service
should not be used to identify a particular address or household.
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.
City 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
print($record->traits->network . "\n"); // '128.101.101.101/32'
Anonymous IP 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-Anonymous-IP.mmdb');
$record = $reader->anonymousIp('128.101.101.101');
if ($record->isAnonymous) { print "anon\n"; }
print($record->ipAddress . "\n"); // '128.101.101.101'
print($record->network . "\n"); // '128.101.101.101/32'

print($record->network . "\n"); // '128.101.101.101/32'
Web Service Client
Usage
To use this API, you must create a new \GeoIp2\WebService\Client
object with your $accountId 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 account 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", "insights".
$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
print($record->traits->network . "\n"); // '128.101.101.101/32'
Values to use for Database or Array Keys
We strongly discourage you from using a value from any names property as
a key in a database or array.
These names may change between releases. Instead we recommend using one of the
following:
GeoIp2\Record\City-$city->geonameIdGeoIp2\Record\Continent-$continent->codeor$continent->geonameIdGeoIp2\Record\CountryandGeoIp2\Record\RepresentedCountry-
$country->isoCodeor$country->geonameIdGeoIp2\Record\Subdivision-$subdivision->isoCodeor$subdivision->geonameId
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 Precision 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.
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.
