title: When should I use closeCursor() for PDO statements?
body: <p><a href="http://php.net/pdostatement.closecursor.php" rel="noreferrer">The PHP documentation on <code>closeCursor()</code></a> says that it</p>
  
  <blockquote>
    <p>frees up the connection to the server so that other SQL statements may be issued, but leaves the statement in a state that enables it to be executed again.</p>
  </blockquote>
  
  <p>When I have used the command though it doesn't seem to matter if it is there or not in between my query statements, and I am beginning to wonder if I need it at all. </p>
  
  <p>Is it different to use it for database calls that don't return data vs. those that do?</p>
