symfony twig数组键显示

I am trying to get the data from the db using array index however i do not want to iterate.

content table:

|id|      content          |active
|1|this is first content   |yes
|2| This is secound Content| yes

Controller.php:

$em = $this->getDoctrine()->getManager();
$entities= $em->getRepository('TestCMSBundle:Content\Content')->GetContents();

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

mytwig:

{{ entities.content[0] }}

some other contents.... blah blah

{{ entities.content[1]}}

but i canot seems to get the content.

Error: Key "content" for array with keys "0, 1" does not exist in TestCMSBundle:index.html.twig at line 80

please i do not want to iterate over the loop like:

{% for entity in entities %}
{{ entity.content}}
{%endfor%}

    You should use dots instead of brackets:

    entities.0.content
