Relative include files
<p>I have a file </p>

<p>workers/activity/bulk_action.php which includes a file</p>

<pre><code>include('../../classes/aclass.php');
</code></pre>

<p>Inside aclass.php it does:</p>

<pre><code>include ('../tcpdf/config/lang/eng.php');
</code></pre>

<p>It seems that the include in the second file is using the first files working directory instead of being relative to itself, resulting in an error. How does this work?</p>
