NAME
|
||||
GeoIP2 - PHP API for MaxMind's GeoIP2 Precision web services and GeoIP2
|
||||
databases
|
||||
|
||||
VERSION
|
||||
version 0.01
|
||||
|
||||
DESCRIPTION
|
||||
Currently, this distribution provides an API for the GeoIP2 Precision web
|
||||
services (as documented at http://dev.maxmind.com/geoip/precision).
|
||||
|
||||
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.
|
||||
|
||||
INTEGRATION WITH GEONAMES
|
||||
GeoNames (http://www.geonames.org/) 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 "geoname_id", which is an integer.
|
||||
|
||||
Many of the records returned by the GeoIP2 web services and databases
|
||||
include a "geoname_id" field. 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 at
|
||||
http://www.maxmind.com/en/correction.
|
||||
|
||||
If you find some other sort of mistake, like an incorrect spelling,
|
||||
please check the GeoNames site (http://www.geonames.org/) 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 at
|
||||
http://www.maxmind.com/en/support for help.
|
||||
|
||||
PHP VERSION SUPPORT
|
||||
This code requires PHP 5.3 or greater. Older versions of PHP are not
|
||||
supported.

# GeoIP2 PHP API #
|
||||
|
||||
## Description ##
|
||||
|
||||
Currently, this distribution provides an API for the GeoIP2 web services
|
||||
(as documented at http://dev.maxmind.com/geoip/precision).
|
||||
|
||||
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.
|
||||
|
||||
## Usage ##
|
||||
|
||||
The basic API for this class is the same for all of the web service end
|
||||
points. First you create a web service client object with your MaxMind
|
||||
``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.
|
||||
|
||||
## Example ##
|
||||
|
||||
>>> use \GeoIP2\Webservice\Client;
|
||||
>>> $client = new Client(42, 'abcdef123456');
|
||||
>>> $omni = $client.omni('24.24.24.24');
|
||||
>>> $country = $omni.country;
|
||||
>>> echo $country.isoCode;
|
||||
|
||||
## Exceptions ##
|
||||
|
||||
For details on the possible errors returned by the web service itself, see
|
||||
http://dev.maxmind.com/geoip2/geoip/web-services for 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 webservice 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\GenericException```.
|
||||
|
||||
## 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 http://dev.maxmind.com/geoip/precision for details on what data each end
|
||||
point may return.
|
||||
|
||||
The only piece of data which is always returned is the :py:attr:`ip_address`
|
||||
attribute in the :py:class:`geoip2.records.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 (http://www.geonames.org/) 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 at
|
||||
http://www.maxmind.com/en/correction.
|
||||
|
||||
If you find some other sort of mistake, like an incorrect spelling,
|
||||
please check the GeoNames site (http://www.geonames.org/) 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 at
|
||||
http://www.maxmind.com/en/support for help.
