Get value with Twig for loop from array

Question

I have an array like this

'contents' => array(
              'row' => array(
                    'col-xs-6' => 'grid 1',
                    'col-xs-6' => 'grid 2'
              ),
              'row' => array(
                    'col-xs-6' => 'grid 3',
                    'col-xs-6' => 'grid 4'
              )
        )

Now I want to get the key from the array but failed, I have try with this code

{% for key, values in contents %}
     <div class="{{ key }}">
          {% for klass, contain in values %}
                 <div class="{{ klass }}">
                      {{ contain }}
                 </div>
          {% endfor %}
     </div>
{% endfor %}

Output:

<div class="row"><div class="col-xs-6">grid 4</div></div>

I don't know why it only appear once, but if I try changing the key name with different value and it works. Please help me. Thank you.

Did @Thamilan's answer provide you with the answer you needed? Or do you just want to have "row" appear as the 1st class in the 1st div tag, and "col-xs-6" in the 2nd div tag, and then the name within the 2nd div being "grid 1"... If so, there might be an easier answer. Or maybe your contents array is fixed? — Alvin Bunk

@AlvinBunk Yes, he did but he not give me a solution, so I can't accept it as an answer. And yes, I want 'row' as the 1st class and 'col-xs-6' as the 2nd class in the 2nd div tag. So, how I can displays it as what the array looks like regardless array name conflict ? — K. Pradnyana

I was thinking you could use Twig's length function on the array, but that probably only works for a valid PHP array. Is there a way to pass in the number of grid values as a number variable? If so, there's a better answer. Let me know. — Alvin Bunk

PHP array should have unique keys.

In your case,

First row gets replaced by second row
First col-xs-6 in the second row will be replaced by second col-xs-6

So, your resultant array would be:

'contents' => array(
      'row' => array(
            'col-xs-6' => 'grid 4'
      )
)

Based on your comments:

So let's say you pass in a variable called gridCount, then in Twig you can code like so:

{% for i in 0..gridCount %}
    <div class="row"><div class="col-xs-6">grid {{ i }}</div></div>
{% endfor %}

Let me know if you also plan to change the class values. In the above, I presume you don't need to. But if they are also dynamic, then you need to tell me how they change.

Good idea, maybe I don't need the class values because i can divided it by 12 and make the result as class. Thank you !
