title: mysqli - Do I really need to do $result->close(); & $mysqli->close();?
body: <p>Just started using mysqli. If I'm working with small data sets on small websites (traffic-wise), do I really need to use these all the time?</p>
  
  <pre><code>$result-&gt;close(); 
  $mysqli-&gt;close();
  </code></pre>
  
  <p>Also, for someone doing custom PHP and MySQL work without a framework, is mysqli the general preferred way of interacting with MySQL?</p>
