So now from a twig page if i want to show all available name from the entity class Userinfo , how i can do that.

Example

Contoller

public function indexAction()
{
    $em = $this->getDoctrine()->getManager();
    $entities = $em->getRepository('YourBundle:Entity')->findAll();

    return $this->render('YourBundle:index.html.twig', array('entities ' => $entities ));
}

Twig

{% for entity in entities %}

        {{ entity.name }}<br>

{% endfor %}

Plain and simple, you pass the collection to the template:

public function someAction()
{
    $usersInfos = $this->getDoctrine()
                       ->getRepository('YourBundle:UserInfo')
                       ->findAll();

    return $this->render('YourBundle:your_template.twig', array(
        'usersInfos' => $usersInfos
    ));
}

To render a table in your_template.twig

<table>
  <thead>
    <th>name</th>
    <th>guid</th>
    <th>status</th>
  </thead>
  <tbody>
    {% for userInfo in usersInfos %}
    <tr>
      <td>{{ userInfo.name }}</td>
      <td>{{ userInfo.guid }}</td>
      <td>{{ userInfo.status }}</td>
    </tr>
    {% else %}
    <tr>
        <h2>Empty!</h2>
    </tr>
    {% endfor %}
  </tbody>
</table>
