find the closest next hour
<p>how can I find the next closest hour in php</p>

<p>so for example if current time is 4:15 the next hour will be 5, etc</p>

<pre><code>$dateString = 'Tue, 13 Mar 2012 04:48:34 -0400';
$date = new DateTime( $dateString );
echo $date-&gt;format( 'H:i:s' );
</code></pre>

<p>gives me the time from the string and I want to expand on that and get the next closest hour</p>
