What is this php supposed to do?
<p>I found this code below in a script, I am trying to figure out if it is actually supposed to do more then I am seeing,
 As far as I can tell it results in an array of:</p>

<p>$maxSize[0] with $new_width<br />
$maxSize[1] with $source_width</p>

<pre><code>$maxSize = array($new_width ? $new_width : $source_width, $new_height ? $new_height : $source_height);
</code></pre>
