My simple PHP includes aren't being parsed
<p>I'm fairly decent with HTML and CSS, but I'm a total noob to PHP. I'm trying to set up a really basic PHP template on my website, which is currently at <a href="http://www.paulgrantdesign.com/test77/photography" rel="nofollow">http://www.paulgrantdesign.com/test77/photography</a></p>

<p>If you use Inspect Element on the page, it looks commented out in Chrome, or isn't even visible in Firefox, so you might have to view source. But I added the line </p>

<pre><code>&lt;?php include('includes/header.php'); ?&gt;
</code></pre>

<p>near the top. The php file exists, which contains a copied and pasted section of what was there before. When everything was in place just in the html file, it looked great. How come the PHP isn't including the file I'm asking it to?</p>
