Example

<?php

require __DIR__ . '/examples/_bootstrap.php';

use Amp\DoH;
use Amp\Dns;
use Amp\Dns\DnsRecord;

use function Amp\Future\awaitFirst;

// Set default resolver to DNS-over-HTTPS resolver
$DohConfig = new DoH\DoHConfig([new DoH\DoHNameserver('https://mozilla.cloudflare-dns.com/dns-query')]); // Defaults to DoH\DoHNameserverType::RFC8484_POST
Dns\dnsResolver(new DoH\Rfc8484StubDoHResolver($DohConfig));

$githubIpv4 = Dns\resolve("github.com", DnsRecord::A);
