README

A DNS client library purely implemented in PHP, compatible with PHP 7.2+.

This is a work in progress. These are the Resource Record types currently understood by the library:

• A
• AAAA
• CNAME
• NS
• SRV
• MX
• SOA
• PTR

Processing responses with other types of Resource Records currently will result in an exception.

Install

Via Composer:

$ composer require carlosafonso/php-dns-client

Usage

The Client class it the main entry point to consume the library. Client instances allow to send Request objects to a name server for resolution using the query() method:

require __DIR__ . '/vendor/autoload.php';

$client = new Afonso\Dns\Client();

// Let's make an A request for example.com
$request = new Afonso\Dns\Request('google.com', Afonso\Dns\ResourceRecord::TYPE_A);

// Let's send it to name server 8.8.8.8
$response = $client->query($request, '8.8.8.8');

$response->getResourceRecords()[0]; // Instance of AResourceRecord
$response->getResourceRecords()[0]->__toString(); // "216.58.211.238"
