MaxMind DB is a binary file +format that stores data indexed by IP address subnets (IPv4 or IPv6). + +## Installation (Composer) ## + +We recommend installing this package with [Composer](https://getcomposer.org/). + +### Download Composer ### + +To download Composer, run in the root directory of your project: + +```bash +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 maxmind-db/reader:~1.0 +``` + +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: + +```php +require 'vendor/autoload.php'; +``` + +## Installation (Standalone) ## + +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, + +```php +require('/path/to/MaxMind-DB-Reader-php/autoload.php'); +``` + +and then instantiate the reader class normally: + +```php +use MaxMind\Db\Reader; +$reader = new Reader('example.mmdb'); +``` + +## Installation (RPM) + +RPMs are available in the [official Fedora repository](https://apps.fedoraproject.org/packages/php-maxminddb). + +To install on Fedora, run: + +```bash +dnf install php-maxminddb +``` + +To install on CentOS or RHEL 7, first [enable the EPEL repository](https://fedoraproject.org/wiki/EPEL) +and then run: + +```bash +yum install php-maxminddb +``` + +Please note that these packages are *not* maintained by MaxMind. + +## Usage ## + +## Example ## + +```php +get($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. + +### Installing Extension ### + +First install [libmaxminddb](https://github.com/maxmind/libmaxminddb) as +described in its [README.md +file](https://github.com/maxmind/libmaxminddb/blob/master/README.md#installing-from-a-tarball). +After successfully installing libmaxmindb, 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 `php.ini` file: + +``` +extension=maxminddb.so +``` + +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. + +## Support ## + +Please report all issues with this code using the [GitHub issue tracker](https://github.com/maxmind/MaxMind-DB-Reader-php/issues). + +If you are having an issue with a MaxMind service that is not specific to the +client API, please see [our support page](https://www.maxmind.com/en/support). + +## Requirements ## + +This library requires PHP 5.6 or greater. + +The GMP or BCMath extension may be required to read some databases +using the pure PHP API. + +## Contributing ## + +Patches and pull requests are encouraged. All code should follow the PSR-1 and +PSR-2 style guidelines. Please include unit tests whenever possible. + +## Versioning ## + +The MaxMind DB Reader PHP API uses [Semantic Versioning](https://semver.org/). + +## Copyright and License ## + +This software is Copyright (c) 2014-2019 by MaxMind, Inc. + +This is free software, licensed under the Apache License, Version 2.0. diff --git a/vendor/maxmind-db/reader/autoload.php b/vendor/maxmind-db/reader/autoload.php new file mode 100644 index 0000000..c79126f --- /dev/null +++ b/vendor/maxmind-db/reader/autoload.php @@ -0,0 +1,45 @@ +class. + * + * @param string $class + * the name of the class to load + */ +function mmdb_autoload($class) +{ + /* + * A project-specific mapping between the namespaces and where + * they're located.
