CHANGELOG
|
||||
=========
|
||||
|
||||
1.10.1 (2021-04-14)
|
||||
-------------------
|
||||
|
||||
* Fix a `TypeError` exception in the pure PHP reader when using large
|
||||
databases on 32-bit PHP builds with the `bcmath` extension. Reported
|
||||
by dodo1708. GitHub #124.
|
||||
|
||||
1.10.0 (2021-02-09)
|
||||
-------------------
|
||||
|
||||
* When using the pure PHP reader, unsigned integers up to PHP_MAX_INT
|
||||
will now be integers in PHP rather than strings. Previously integers
|
||||
greater than 2^24 on 32-bit platforms and 2^56 on 64-bit platforms
|
||||
would be strings due to the use of `gmp` or `bcmath` to decode them.
|
||||
Reported by Alejandro Celaya. GitHub #119.
|
||||
|
||||
1.9.0 (2021-01-07)
|
||||
------------------
|
||||
|
||||
* The `maxminddb` extension is now buildable on Windows. Pull request
|
||||
by Jan Ehrhardt. GitHub #115.
|
||||
|
||||
1.8.0 (2020-10-01)
|
||||
------------------
|
||||
|
||||
* Fixes for PHP 8.0. Pull Request by Remi Collet. GitHub #108.
|
||||
|
||||
1.7.0 (2020-08-07)
|
||||
------------------
|
||||
|
||||
* IMPORTANT: PHP 7.2 or greater is now required.
|
||||
* The extension no longer depends on the pure PHP classes in
|
||||
`maxmind-db/reader`. You can use it independently.
|
||||
* Type hints have been added to both the pure PHP implementation
|
||||
and the extension.
|
||||
* The `metadata` method on the reader now returns a new copy of the
|
||||
metadata object rather than the actual object used by the reader.
|
||||
* Work around PHP `is_readable()` bug. Reported by Ben Roberts. GitHub
|
||||
#92.
|
||||
* This is the first release of the extension as a PECL package.
|
||||
GitHub #34.
|
||||
|
||||
1.6.0 (2019-12-19)
|
||||
------------------
|
||||
|
||||
* 1.5.0 and 1.5.1 contained a possible memory corruptions when using
|
||||
`getWithPrefixLen`. This has been fixed. Reported by proton-ab.
|
||||
GitHub #96.
|
||||
* The `composer.json` file now conflicts with all versions of the
|
||||
`maxminddb` C extension less than the Composer version. This is to
|
||||
reduce the chance of having an older, conflicting version of the
|
||||
extension installed. You will need to upgrade the extension before
|
||||
running `composer update`. Pull request by Benoît Burnichon. GitHub
|
||||
#97.
|
||||
|
||||
1.5.1 (2019-12-12)
|
||||
------------------
|
||||
|
||||
* Minor performance improvements.
|
||||
* Make tests pass with older versions of libmaxminddb. PR by Remi
|
||||
Collet. GitHub #90.
|
||||
* Test enhancements. PR by Chun-Sheng, Li. GitHub #91.
|
||||
|
||||
1.5.0 (2019-09-30)
|
||||
------------------
|
||||
|
||||
* PHP 5.6 or greater is now required.
|
||||
* The C extension now supports PHP 8. Pull request by John Boehr.
|
||||
GitHub #87.
|
||||
* A new method, `getWithPrefixLen`, was added to the `Reader` class.
|
||||
This method returns an array containing the record and the prefix
|
||||
length for that record. GitHub #89.
|
||||
|
||||
1.4.1 (2019-01-04)
|
||||
------------------
|
||||
|
||||
* The `maxminddb` extension now returns a string when a `uint32`
|
||||
value is greater than `LONG_MAX`. Previously, the value would
|
||||
overflow. This generally only affects 32-bit machines. Reported
|
||||
by Remi Collet. GitHub #79.
|
||||
* For `uint64` values, the `maxminddb` extension now returns an
|
||||
integer rather than a string when the value is less than or equal
|
||||
to `LONG_MAX`. This more closely matches the behavior of the pure
|
||||
PHP reader.
|
||||
|
||||
1.4.0 (2018-11-20)
|
||||
------------------
|
||||
|
||||
* The `maxminddb` extension now has the arginfo when using reflection.
|
||||
PR by Remi Collet. GitHub #75.
|
||||
* The `maxminddb` extension now provides `MINFO()` function that
|
||||
displays the extension version and the libmaxminddb version. PR by
|
||||
Remi Collet. GitHub #74.
|
||||
* The `maxminddb` `configure` script now uses `pkg-config` when
|
||||
available to get libmaxmindb build info. PR by Remi Collet.
|
||||
GitHub #73.
|
||||
* The pure PHP reader now correctly decodes integers on 32-bit platforms.
|
||||
Previously, large integers would overflow. Reported by Remi Collet.
|
||||
GitHub #77.
|
||||
* There are small performance improvements for the pure PHP reader.
|
||||
|
||||
1.3.0 (2018-02-21)
|
||||
------------------
|
||||
|
||||
* IMPORTANT: The `maxminddb` extension now obeys `open_basedir`. If
|
||||
`open_basedir` is set, you _must_ store the database within the
|
||||
specified directory. Placing the file outside of this directory
|
||||
will result in an exception. Please test your integration before
|
||||
upgrading the extension. This does not affect the pure PHP
|
||||
implementation, which has always had this restriction. Reported
|
||||
by Benoît Burnichon. GitHub #61.
|
||||
* A custom `autoload.php` file is provided for installations without
|
||||
Composer. GitHub #56.
|
||||
|
||||
1.2.0 (2017-10-27)
|
||||
------------------
|
||||
|
||||
* PHP 5.4 or greater is now required.
|
||||
* The `Reader` class for the `maxminddb` extension is no longer final.
|
||||
This was change to match the behavior of the pure PHP class.
|
||||
Reported and fixed by venyii. GitHub #52 & #54.
|
||||
|
||||
1.1.3 (2017-01-19)
|
||||
------------------
|
||||
|
||||
* Fix incorrect version in `ext/php_maxminddb.h`. GitHub #48.
|
||||
|
||||
1.1.2 (2016-11-22)
|
||||
------------------
|
||||
|
||||
* Searching for database metadata only occurs within the last 128KB
|
||||
(128 * 1024 bytes) of the file, speeding detection of corrupt
|
||||
datafiles. Reported by Eric Teubert. GitHub #42.
|
||||
* Suggest relevant extensions when installing with Composer. GitHub #37.
|
||||
|
||||
1.1.1 (2016-09-15)
|
||||
------------------
|
||||
|
||||
* Development files were added to the `.gitattributes` as `export-ignore` so
|
||||
that they are not part of the Composer release. Pull request by Michele
|
||||
Locati. GitHub #39.
|
||||
|
||||
1.1.0 (2016-01-04)
|
||||
------------------
|
||||
|
||||
* The MaxMind DB extension now supports PHP 7. Pull request by John Boehr.
|
||||
GitHub #27.
|
||||
|
||||
1.0.3 (2015-03-13)
|
||||
------------------
|
||||
|
||||
* All uses of `strlen` were removed. This should prevent issues in situations
|
||||
where the function is overloaded or otherwise broken.
|
||||
|
||||
1.0.2 (2015-01-19)
|
||||
------------------
|
||||
|
||||
* Previously the MaxMind DB extension would cause a segfault if the Reader
|
||||
object's destructor was called without first having called the constructor.
|
||||
(Reported by Matthias Saou & Juan Peri. GitHub #20.)
|
||||
|
||||
1.0.1 (2015-01-12)
|
||||
------------------
|
||||
|
||||
* In the last several releases, the version number in the extension was
|
||||
incorrect. This release is being done to correct it. No other code changes
|
||||
are included.
|
||||
|
||||
1.0.0 (2014-09-22)
|
||||
------------------
|
||||
|
||||
* First production release.
|
||||
* In the pure PHP reader, a string length test after `fread()` was replaced
|
||||
with the difference between the start pointer and the end pointer. This
|
||||
provided a 15% speed increase.
|
||||
|
||||
0.3.3 (2014-09-15)
|
||||
------------------
|
||||
|
||||
* Clarified behavior of 128-bit type in documentation.
|
||||
* Updated phpunit and fixed some test breakage from the newer version.
|
||||
|
||||
0.3.2 (2014-09-10)
|
||||
------------------
|
||||
|
||||
* Fixed invalid reference to global class RuntimeException from namespaced
|
||||
code. Fixed by Steven Don. GitHub issue #15.
|
||||
* Additional documentation of `Metadata` class as well as misc. documentation
|
||||
cleanup.
|
||||
|
||||
0.3.1 (2014-05-01)
|
||||
------------------
|
||||
|
||||
* The API now works when `mbstring.func_overload` is set.
|
||||
* BCMath is no longer required. If the decoder encounters a big integer,
|
||||
it will try to use GMP and then BCMath. If both of those fail, it will
|
||||
throw an exception. No databases released by MaxMind currently use big
|
||||
integers.
|
||||
* The API now officially supports HHVM when using the pure PHP reader.
|
||||
|
||||
0.3.0 (2014-02-19)
|
||||
------------------
|
||||
|
||||
* This API is now licensed under the Apache License, Version 2.0.
|
||||
* The code for the C extension was cleaned up, fixing several potential
|
||||
issues.
|
||||
|
||||
0.2.0 (2013-10-21)
|
||||
------------------
|
||||
|
||||
* Added optional C extension for using libmaxminddb in place of the pure PHP
|
||||
reader.
|
||||
* Significantly improved error handling in pure PHP reader.
|
||||
* Improved performance for IPv4 lookups in an IPv6 database.
|
||||
|
||||
0.1.0 (2013-07-16)
|
||||
------------------
|
||||
|
||||
* Initial release

|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.

|
||||
with Licensor regarding such Contributions.

|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||

||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,

||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

||||
implied, including, without limitation, any warranties or conditions

|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|

# MaxMind DB Reader PHP API #
|
||||
|
||||
## Description ##
|
||||
|
||||
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).
|
||||
|
||||
## 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
|
||||
<?php
|
||||
require_once 'vendor/autoload.php';
|
||||
|
||||
use MaxMind\Db\Reader;
|
||||
|
||||
$ipAddress = '24.24.24.24';
|
||||
$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.
|
||||
|
||||
### Installing Extension ###
|
||||
|
||||
First install [libmaxminddb](https://github.com/maxmind/libmaxminddb) as
|
||||
described in its [README.md
|
||||
file](https://github.com/maxmind/libmaxminddb/blob/main/README.md#installing-from-a-tarball).
|
||||
After successfully installing libmaxmindb, you may install the extension
|
||||
from [pecl](https://pecl.php.net/package/maxminddb):
|
||||
|
||||
```
|
||||
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 `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 7.2 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.
|
||||
|
||||
