How to tell which PHP file was used to "include" another?
<p>In PHP when using the include function is the a way to tell from the inserted file which file inserted you? For example, I use the following line often through my code:</p>

<pre><code>include 'header.php';
</code></pre>

<p>Is there a way to tell from inside header.php what PHP file inserted you?</p>
