README

Provides a DNSRecordGetterInterface to allow you to use custom DNS servers with mika56/spfcheck.

It uses purplepixie/phpdns to get the DNS records.

All the code was initially written by @btafoya and extracted from the main repository to this one.

Installation

Ensure you have mika56/spfcheck installed, then require mika56/spfcheck-dns-direct:

composer require "mika56/spfcheck-dns-direct:^2.0"

Usage

Instantiate a new Mika56\SPFCheckDNSDirect\DNSRecordGetterDirect object and pass it to your Mika56\SPFCheck\SPFCheck object:

<?php
use Mika56\SPFCheck\SPFCheck;
use Mika56\SPFCheckDNSDirect\DNSRecordGetterDirect;

require('vendor/autoload.php');

$checker = new SPFCheck(new DNSRecordGetterDirect());
var_dump($checker->getIPStringResult('127.0.0.1', 'test.com'));

Note that by default, Google's 8.8.8.8 DNS servers are used. You can change this by passing arguments to the constructor:

public function __construct(
    string $nameserver = '8.8.8.8',
    int $port = 53,
    int $timeout = 30,
    bool $udp = true,
    bool $tcpFallback = true
)
