title: PHP - dns_get_record - Why is DNS_PTR always returning an empty array?
body: <p>I am trying to obtain ptr records for a domain.</p>
  
  <p>For some reason when i try to do this using dns_get_record it is constantly coming back as empty.</p>
  
  <p>I did try this originally and got a whole range of results but now its just returning an empty array every time... Could someone suggest the reason behind this behaviour?</p>
  
  <pre><code>$result = dns_get_record("webstorm.co.za", DNS_PTR);
  print_r($result);
  </code></pre>
  
  <p>outputs :</p>
  
  <pre><code>Array()
  </code></pre>
  
  <p>When it would be populated with values?</p>
  
  <p>Any suggestions, advice or feedback would be greatly appreciated as i cannot for the life of my figure out why this is happening now!</p>
