Creating an array within for loop with Twig

Question

I\'m trying to create an array and store values in it within for loop but failed so far. How can I do it with Twig?

I\'ve read these but being new in Twig makes it hard

Answer 1

I have other solution for arrays in loop. This solution is letting you to make arrays like PHP:

$my_array[] = array('key_1' => $value1, 'key_2' => $value_2);

in this case:

{% set cars_details = [] %}
{% for car in cars %}
     <!-- This is the line of code that does the magic -->
    {% set car = car|merge({(loop.index0) : {'color': car.color, 'year': car.year} }) %}
{% endfor %}
{{ car|dump }}

Answer 2

Solved by following Vision's suggestion:

{% set brands = [] %}
{% for car in cars %}
    {% if car not in brands %}
        {% set brands = brands|merge([car]) %}
    {% endif %}
{% endfor %}

{% for brand in brands %}
   {{ brand }}
{% endfor %}

Also I'll take bartek's comment into consideration next time. This was one off.
