Clearing _POST array fully
<p>I want clear $_POST array content fully, all examples what I see in internet, looks like this:</p>

<pre><code>if (count($_POST) &gt; 0) {
    foreach ($_POST as $k=&gt;$v) {
        unset($_POST[$k]);
    }
}
</code></pre>

<p>Tell please, this variant will be not more better? (Point of view as saving resources)</p>

<pre><code>if (count($_POST) &gt; 0) {
     $_POST = array();
}
</code></pre>

<p>or not ?</p>
