title: What is the correct path to a file "below" the root?
body: <p>I have a bitnami Wordpress installation. When navigating via FTP, the directory tree to Wordpress is home/bitnami/apps/wordpress/htdocs. When browsing, this acts as the root directory. </p>
  
  <p>I have added several packages I need to use via Composer (AWS SDK, Facebook SDK, etc.) Composer installs these packages at home/bitnami/vendor. I can't seem to find the right path to these files. </p>
  
  <p>I created a file called "test.php" in a subdirectory of the Wordpress root called test-dir (home/bitnami/apps/wordpress/htdocs/test-dir/test.php). I want to require the file home/bitnami/vendor/required.php in test.php. What would be the correct path to required.php? Here is my first guess (which throws an HTTP ERROR 500):</p>
  
  <p>test.php:</p>
  
  <pre><code>&lt;?php
  require '../../../../vendor/required.php';
  </code></pre>
  
  <p>What is the correct path?</p>
