MaxMind DB Reader PHP API
This is the PHP API for reading MaxMind DB files. MaxMind DB is a binary file format that stores data indexed by IP address subnets (IPv4 or IPv6).
We recommend installing this package with 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.
Run in your project root:
php composer.phar require maxmind-db/reader:~1.0
You should now have the files
composer.lock as well as
vendor in your project directory. If you use a version control
composer.json should be added to it.
After installing the dependencies, you need to require the Composer autoloader from your code:
If you don't want to use Composer for some reason, a custom
autoload.php is provided for you in the project root. To use the
library, simply include that file,
and then instantiate the reader class normally:
use MaxMind\Db\Reader; $reader = new Reader('example.mmdb');
RPMs are available in the official Fedora repository.
To install on Fedora, run:
dnf install php-maxminddb
To install on CentOS or RHEL 7, first enable the EPEL repository and then run:
yum install php-maxminddb
Please note that these packages are not maintained by MaxMind.
<?php require_once 'vendor/autoload.php'; use MaxMind\Db\Reader; $ipAddress = '18.104.22.168'; $databaseFile = 'GeoIP2-City.mmdb'; $reader = new Reader($databaseFile); // get returns just the record for the IP address print_r($reader->get($ipAddress)); // getWithPrefixLen returns an array containing the record and the // associated prefix length for that record. print_r($reader->getWithPrefixLen($ipAddress)); $reader->close();
Optional PHP C Extension
MaxMind provides an optional C extension that is a drop-in replacement for
MaxMind\Db\Reader. In order to use this extension, you must install the
Reader API as described above and install the extension as described below. If
you are using an autoloader, no changes to your code should be necessary.
pecl install maxminddb
Alternatively, you may install it from the source. To do so, run the following commands from the top-level directory of this distribution:
cd ext phpize ./configure make make test sudo make install
You then must load your extension. The recommend method is to add the
following to your
Note: You may need to install the PHP development package on your OS such as php5-dev for Debian-based systems or php-devel for RedHat/Fedora-based ones.
128-bit Integer Support
The MaxMind DB format includes 128-bit unsigned integer as a type. Although no MaxMind-distributed database currently makes use of this type, both the pure PHP reader and the C extension support this type. The pure PHP reader requires gmp or bcmath to read databases with 128-bit unsigned integers.
The integer is currently returned as a hexadecimal string (prefixed with "0x") by the C extension and a decimal string (no prefix) by the pure PHP reader. Any change to make the reader implementations always return either a hexadecimal or decimal representation of the integer will NOT be considered a breaking change.
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.
This library requires PHP 7.2 or greater.
The GMP or BCMath extension may be required to read some databases using the pure PHP API.
Patches and pull requests are encouraged. All code should follow the PSR-1 and PSR-2 style guidelines. Please include unit tests whenever possible.
The MaxMind DB Reader PHP API uses Semantic Versioning.
