title: Symfony get Values from Entity
body: <p>Is there a possibility to read all available Values from an entity?</p>
  
  <p>E.G.</p>
  
  <pre><code>class Properties
  {
      /**
       * @var integer
       *
       * @ORM\Column(name="id", type="integer")
       * @ORM\Id
       * @ORM\GeneratedValue(strategy="AUTO")
       */
      private $id;
  
      /**
       * @var string
       *
       * @ORM\Column(name="UserID", type="string", length=255)
       */
      private $userID;
  
      /**
       * @var string
       *
       * @ORM\Column(name="Sport", type="string", length=1)
       */
      private $sport;
  
  .
  .
  .
  </code></pre>
  
  <p>So that I will get the name of the Value like: Id, UserID, Sport?</p>
