dns over https handler in php lol LOL, connects to 1.1.1.1 by default, only tested/known to work with Apple platforms

dns.php

<?php

// target dns server to connect to
define('DNS_TARGET_ADDRESS', 'udp://1.1.1.1:53');

// dns will usually be either a get param, a post param, or both (hence request)
if(!isset($_REQUEST['dns'])) {
	// show an error
	http_response_code(400);
	header('Content-Type: text/plain; charset=UTF-8');
	// explanation
	exit("this is a dns over https handler (in 😹😹 php 😹😹) and it expects you to pass either a get or post parameter called \"dns\" that contains a standard dns request and that parameter was not found 🙁!");
}

// decode and undo any base64 url encoding i believe
$request = base64_decode(str_replace(array('-', '_'), array('+', '/'), $_REQUEST['dns']));
// set header for dns message cause yknow, You Gotta,
header('Content-Type: application/dns-message');
// connect to dns and do request
$sock = @stream_socket_client(DNS_TARGET_ADDRESS, $errno, $errstr);
if(!$sock) {
	http_response_code(502);
	header('Content-Type: text/plain');
	exit('errno ' . $errno . ': ' . $errstr);
}
// ya
fwrite($sock, $request);
echo fread($sock, 4096);
fclose($sock);
