a simple php logic
<p>I just saw this source code on a website, but I don't know what it means, can anyone tell me what it is? thank you so much.</p>

<pre><code>private function buildCache()
{
    !empty($this-&gt;cache_list) &amp;&amp; $this-&gt;cache-&gt;loadCache($this-&gt;cache_list);
}
</code></pre>
