Symfony2 / Twig - getting array from dynamic array key

Question

In PHP I would do this:

foreach( $array as $key => $value ) {

    echo $another_array[$key];

}

I can't see how to do that in Twig (in Symfony2). I've tried various things, but this would seem the obvious answer, but it doesn't work. It returns a 'Item "the_index" for "Array" does not exist in' error.

{% for value in array %}

    {% set the_index = loop.index %}
    {{ another_array.the_index }}

Any ideas?

The fastest way:

{% for key,value in array %}
  {{ another_array[key] }}
{% endfor %}

Great. I used that to compose the element name of a dynamically generated form. form_row(form["element_#{element.id}"])

You can use the attribute function.

{{ attribute(another_array, the_index) }}

<ul>
    {% for value in array %}
       {% set the_index = attribute(another_array,  loop.index) %}
       <li>{{ the_index }}</li>
    {% endfor %}
</ul>
