PHP : Function Reference : GeoIP Functions

GeoIP Functions


The GeoIP extension allows you to find the location of an IP address. City, State, Country, Longitude, Latitude, and other information as all, such as ISP and connection type can be obtained with the help of GeoIP.


This extension requires the GeoIP C library version 1.4.0 or higher to be installed. You can grab the latest version from » and compile it yourself.

By default, you will only have access to the Free GeoIP Country or GeoLite City databases. While this module can work with other types of database, you must buy a commercial license from » Maxmind.


This » PECL extension is not bundled with PHP.

Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: »

Resource Types

This extension has no resource types defined.

Predefined Constants

The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.


The following constants are for net speed:


Table of Contents

geoip_country_code_by_name — Get the two letter country code
geoip_country_code3_by_name — Get the three letter country code
geoip_country_name_by_name — Get the full country name
geoip_database_info — Get GeoIP Database information
geoip_db_avail — Determine if GeoIP Database is available
geoip_db_filename — Returns the filename of the corresponding GeoIP Database
geoip_db_get_all_info — Returns detailed informations about all GeoIP database types
geoip_id_by_name — Get the Internet connection speed
geoip_org_by_name — Get the organization name
geoip_record_by_name — Returns the detailed City information found in the GeoIP Database
geoip_region_by_name — Get the country code and region

Code Examples / Notes » ref.geoip


Try renaming GeoLiteCity.dat to GeoIPCity.dat.


The geoip_country_*_by_name functions only work with GeoIP Country.  The geoip_record_by_name function works with GeoIP City.  geoip_region_by_name works with GeoIP Region.  So the API should work with all of the GeoIP databases, as long as you call the correct function.

php dot comment dot addition

Just to clarify the other comments, the maxmind post seems to be out of date / incorrect.  
This module fails to work (ie: resolve cities) with the GeoLite City database from here:
The error occurs when calling the function geoip_record_by_name(), which states incorrectly that the required database is not available.  I have tested it with the very latest database, for which geoip_database_info() returns  the version:
GEO-533LITE 20070601 Build 1 Copyright (c) 2007 MaxMind LLC All Rights Reserved
It does, however, resolve countries OK via the GeoLite Country database, which you can grab here:
I tested with the version:
GEO-106FREE 20070601 Build 1 Copyright (c) 2007 MaxMind LLC All Rights Reserved

If you want to use this extension in SUSE/openSUSE, it is available here:


If you are a Debian or Ubuntu user, instead of building it from source, you can:
aptitude install libgeoip-dev libgeoip1

I couldn't get it to work with the DMA code database (product ID 137).  It seems to only work with the country database.  The documentation should contain a warning that this code (as of 0.2.0) is incomplete and that Net_GeoIP should be used for non-country databases.


Both, Ubuntu and Debian itself make usage of version 1.3.x of the c libraries, so installation can't be done with the debian packages, because configure stops with:

== configure: error: You need version 1.4.0 or higher of the C API ==
so you must download it from maxmind.
