GeoIP2 PHP API
Beta Note
This is a beta release. The API may change before the first production release, which will be numbered 2.0.0.
You may find information on the GeoIP2 beta release process on our website.
To provide feedback or get support during the beta, please see the MaxMind Customer Community.
Description
Currently, this distribution provides an API for the [GeoIP2 web services] (http://dev.maxmind.com/geoip/geoip2/web-services).
In the future, this distribution will also provide the same API for the GeoIP2 downloadable databases. These databases have not yet been released as a downloadable product.
See GeoIP2\WebService\Client
for details on the web service client
API.
Installation
Define Your Dependencies
We recommend installing this package with Composer.
To do this, add geoip2/geoip2
to your composer.json
file.
{
"require": {
"geoip2/geoip2": "0.2.*"
}
}
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';
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.
See the API documentation for more details.
Example
<?php
require_once 'vendor/autoload.php';
use \GeoIP2\WebService\Client;
$client = new Client(42, 'abcdef123456');
$omni = $client->omni('24.24.24.24');
echo $omni->country->isoCode;
Exceptions
For details on the possible errors returned by the web service itself, see the GeoIP2 web service docs.
If the web service returns an explicit error document, this is thrown as a
\GeoIP2\Exception\WebServiceException
. If some other sort of transport
error occurs, this is thrown as a \GeoIP2\Exception\HttpException
.
The difference is that the web service error includes an error message and
error code delivered by the web service. The latter is thrown when some sort
of unanticipated error occurs, such as the web service returning a 500 or an
invalid error document.
If the web service returns any status code besides 200, 4xx, or 5xx, this also
becomes a \GeoIP2\Exception\HttpException
.
Finally, if the web service returns a 200 but the body is invalid, the client
throws a \GeoIP2\Exception\GeoIP2Exception
.
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.
