title: pdo free result
body: <p>there is a mysql function in php called <a href="http://php.net/mysql_free_result" rel="noreferrer">mysql_free_result()</a>;
  I couln't find any similar function for PDO.</p>
  
  <p>is there a pdo function to free the result of a database fetch or does the result set automatically get requested and freed when I call <code>$stmt-&gt;fetch()</code> data?</p>
  
  <p>could someone explain me this difference between native mysql and pdo?</p>
