<?php $Hostname = new DNS("example.com"); ?>

  <?php echo $Hostname->get_hostname(); ?>

Retrieve all the DNS records:

  <?php print_r($Hostname->get_records()); ?>

Only retrive the 'A' records from the DNS server:

  <?php print_r($Hostname->get_records('A')); ?>

  <?php print_r($Hostname->get_records('A', 'MX')); ?>
