title: PHPStorm can't analyse a path from a variable?

  <p>As you see, the first require_once gives no weak warning. The latter one does, but I don't understand why. Is there any reason why this is happening? The file exists and contains a class. If its any useful, this is the file structure:</p>
  
  <pre class="lang-none prettyprint-override"><code>-| Project
    -| Anomius
      - Anomius.php (This is the included file)
    -| Sites
      -| Foo
        - app.php (This is the file on the image)
  </code></pre>
