title: PHP Getting A Records Only Using dns_record
body: <p>I am making an IP grab script for servers and I had some issues with my code. I want to grab just the ip addresses of servers using dns_get_record without the extra bloat in the default output. However, my current script displays a blank output when ran. And no. I can't simply use gethostbyname, as it has to be compatible with querying wan ips for the server the code is running on. Here is my code so far:</p>
  
  <pre><code>&lt;?php
  function test() {
      $host = "google.com";
       $result = dns_get_record("$host", DNS_A);
  foreach ($result as $record) {
      echo $record['target'];
      }
  }
  ?&gt;
  </code></pre>
