title: PhpStorm unable to recognize the Php File
body: <p>I have a PHP trait file : <code>app\Lib\someTrait.php</code></p>
  <p>Even though it is a PHP file (with .php extension), PHPStorm is unable to recognize it as a valid PHP file. The editor is not doing syntax highlighting for PHP code inside this file and it is pretty much displayed as normal text file.</p>
  <p>I am trying to use this file from its namespace in to another class file and there also it is unable to recognize the file path using :</p>
  <pre><code>use app\Lib\someTrait;
  </code></pre>
  <p>I did <code>composer dump-autoload</code> and also :</p>
  <pre><code>File-&gt;Invalid Caches and restart
  </code></pre>
  <p>I also deleted this file and restarted PHPStorm and again added it back but still not able to resolve this issue.</p>
  <p>Looks like something has gone weird when I created a first file with this file name and now even though I tried all option PHPStorm is not treating this file as PHP file.</p>
  <p>But still PHPStorm is unable to recognize this file.</p>
  <p>How can I fix this issue?</p>
