What is show('...') in php?
<p>I hate to ask what may be a simple question, but I'm still new to php and learning as I go. I came across a php file with this snippet that appears to do the same thing as include(), but I can't find documentation on it. </p>

<pre><code>&lt;?php show('header'); ?&gt; 
</code></pre>

<p>Is it custom or am I not looking hard enough? If it is custom, how do I find where it may be defined at so I can understand it better. To my knowledge there's no frameworks being used.</p>
