title: Symfony does not find mongodb driver (DLL)
body: <p>I've installed the mongodb driver (<code>php_mongodb.dll</code>). The file is inside <code>xampp\php\ext</code>. I've used it before with simple connections and queries against my mongodb server and it works perfectly.</p>
  
  <p>To make the connection with mongo I use this simple line:</p>
  
  <p><code>$conn = new MongoDB\Driver\Manager("mongodb://localhost:27017");</code></p>
  
  <p>However, when I try to use it in my symfony project, I get this error:</p>
  
  <blockquote>
    <p>Attempted to load class "Manager" from namespace "AlimentosBundle\Controller\MongoDB\Driver".
    Did you forget a "use" statement for another namespace?</p>
  </blockquote>
  
  <p>I'm very beginner using symfony. Should I import also the DLL inside the symfony project? If not, how could I force Symfony to find the DLL?</p>
  
  <p>I know that doctrine/mongodb bundle actually exists, but I just wanted to try some simple connections, is possible to do it without that bundle?</p>
