get parameter of array in twig loop

Question

When I dump an array in twig, it gives the following result:

 array(1) {
  [0]=>
  object(TEST\Bundle\BlogBundle\Entity\Follow)#364 (3) {
    ["id":"TEST\Bundle\BlogBundle\Entity\Follow":private]=>
    int(1)
    ["follower"]=>
    int(2)
    ["followed"]=>
    int(1)
  }
}

 int(1)

 int(1)

How can I access the follower parameter inside my loop which is:

{% for fol in followers %}

    <pre> {{ dump(fol)  }} </pre>

{% endfor %}

Thank you for your help.

Use TWIG attribute docs. Example:

{% for fol in followers %}
    <pre> {{ dump(attribute(fol[0], follower)) }} </pre>
{% endfor %}

Please make you sure that you have getters for follower in TEST\Bundle\BlogBundle\Entity\Follow or follower attribute is public.

Or simillarly print value:

{% for fol in followers %}
    <pre> {{ fol[0].follower }} </pre>
{% endfor %}

Thank you for your time, but it is still not working, it gives me Variable "follower" does not exist in TESTBlogBundle:Dashboard:Followers.html.twig at line 10. I am new with twig

@whitelettersandblankspaces please provide result of your code. I mean result of <pre> {{ dump(fol) }} </pre>.

Thank you very much. I have getter in my Follow entity, and I have follower as public attribute, but the problem is not resolved, even it is very logical what you are saying.

Error occurs because you have little mess in your array followers. First element of this array (index 0) is object, but second and third (indexes 1 and 2) are integer.
