title: dns_get_record function fails to retrieve domain details
body: <p>I'm trying to retrieve domain details of a domain I'm looking up which I purchased and pointed the nameservers to (which was done more than 72 hours ago). Now, when I'm using the <code>dns_get_record</code> function to look up the details of my domain, e.g.</p>
  
  <pre><code>dns_get_record('www.mydomain.com');
  dns_get_record('mydomain.com');
  </code></pre>
  
  <p>They both just return an empty array with no items or values in it, so I cleared my DNS cache, but this didn't seem to solve the problem. I went to <a href="http://whois.domaintools.com/" rel="nofollow"><code>http://whois.domaintools.com/</code></a> to look up on their side, I can confirm the domain has the correct nameservers pointed to, but not <code>dns_get_record</code> since returning an empty array.</p>
  
  <p>I tried using the <code>dig</code> command and <code>nslookup</code>, I cannot see the nameservers in the output.</p>
  
  <p>How can I find the nameservers of a domain in PHP?</p>
