title: PHPStorm PHPDoc how to declare array parameter that have DateTime object in it?
body: <p>So, I have some method with a parameter expecting an array. Like this:</p>
  
  <pre><code>private function handler($db_data){
      $formatted_date = $db_data['StartDate']-&gt;format('Y-m-d H:i:s');
  }
  </code></pre>
  
  <p>As you can see, this array have DateTime object in it. The problem is that I don't know how to declare this DateTime object using PHPDoc, so PHPStorm is telling me that method 'format' is not found. Anybody know how to solve it? Don't propose to suppress this warning :) Thanks</p>
