PHP DNS Server
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.
Supported Record Types
- Needs either
socket_createPHP extension loaded (which they are by default)
Here is an example of some DNS records
<?php require "vendor/autoload.php"; // JSON formatted DNS records file $record_file = 'dns_record.json'; $jsonResolver = new yswery\DNS\JsonResolver($record_file); // Recursive resolver acting as a fallback to the JsonResolver $recursiveResolver = new yswery\DNS\RecursiveResolver($options); $stackableResolver = new yswery\DNS\StackableResolver(array($jsonResolver, $recursiveResolver)); // Creating a new instance of our class $dns = new yswery\DNS\Server($stackableResolver); // Starting our DNS server $dns->start();
And here is us querying it and seeing the response
$ dig @127.0.0.1 test.com A +short 18.104.22.168 $ dig @127.0.0.1 test.com TXT +short "Some text." $ dig @127.0.0.1 test2.com A +short 22.214.171.124 126.96.36.199
