title: mysqli_free_result necessary?
body: <p>I was looking through my code and read that it was recommened to use <a href="http://www.php.net/manual/en/mysqli-result.free.php" rel="noreferrer"><code>mysqli_free_result</code></a> when your result object is not needed anymore. But after seeing that each query is outputed to the <code>$result</code> variable repeatedly throughout the script, I am wondering if <code>mysqli_free_result</code> would really be necessary. Seems like each time a query is ran the <code>$result</code> variable is already being wiped clean and set to a new result. Just curious if anyone has any input on this.</p>
