This is an Authoritative DNS Server written in pure PHP. It will listen to DNS request on the default port (Default: port 53) and give answers about any domain that it has DNS records for. This class can be used to give DNS responses dynamically based on your pre-existing PHP code.
PHP 7.2+
- Needs either
sockets
orsocket_create
PHP extension loaded (which they are by default)
Here is an example of DNS server usage:
require_once __DIR__.'/../vendor/autoload.php';
// JsonResolver created and provided with path to file with json dns records
$jsonResolver = new yswery\DNS\Resolver\JsonResolver([
'/path/to/zones/example.com.json',
'/path/to/zone/test.com.json',
]);
// System resolver acting as a fallback to the JsonResolver
$systemResolver = new yswery\DNS\Resolver\SystemResolver();
// StackableResolver will try each resolver in order and return the first match
$stackableResolver = new yswery\DNS\Resolver\StackableResolver([$jsonResolver, $systemResolver]);
// Create the eventDispatcher and add the event subscribers
$eventDispatcher = new \Symfony\Component\EventDispatcher\EventDispatcher();
$eventDispatcher->addSubscriber(new \yswery\DNS\Event\Subscriber\EchoLogger());
// Create a new instance of Server class
$server = new yswery\DNS\Server($stackableResolver, $eventDispatcher);
// Start DNS server
$server->start();
- Run
composer install
to install dependencies - Run
php example/example.php
to run the server
Query server using dig
command to ensure proper functioning
$ dig @127.0.0.1 test.com A +short
111.111.111.111
$ dig @127.0.0.1 test.com TXT +short
"Some text."
$ dig @127.0.0.1 test2.com A +short
111.111.111.111
112.112.112.112
PHP DNS Server supports four zone file formats out-of-the-box: Bind, JSON, XML, and YAML; each file format
is supported by a specialised Resolver
class: BindResolver
, JsonResolver
, XmlResolver
, and YamlResolver
,
respectively. Example files are in the example/
directory.

Unit tests using PHPUnit are provided. A simple script is located in the root.
- run
composer install
to install PHPUnit and dependencies - run
vendor/bin/phpunit
from the root to run the tests
- run
composer run-script build-server
to build the phpdnsserver.phar file, outputs in the bin folder. - run
composer run-script build-console
to build the phpdnscli.phar file, outputs in the bin folder. - run
composer run-script build-installer
to build the installer. Windows support for the installer is currently limited.
To run the new .phar files, download them from the release and move them to the desired folder.
phpdnsserver.phar
to run the phpdnsserver, uses the new filesystem by defaultphpdnscli.phar
to run cli commandsphpdnsinstaller.phar
as root to create required folders and default config.
--bind:b
- bind to a specific ip. Uses0.0.0.0
by default--port:p
- bind to a specific port. Uses port53
by default--config:c
- specify the config file. Usesphpdns.json
on windows and/etc/phpdns.json
on unix systems by default--storage:s
- specify the path to the storage for zones, and logs. Uses/etc/phpdnsserver
on unix, and current working directory on windows.
