Twig for loop and array with key

问题:

I use Twig and I have an array with key like this :

array[1] = "alpha"
array[2] = "bravo"
array[3] = "charlie"
array[8] = "delta"
array[9] = "echo"

And I would like to get the key (1,2,3,8,9) and the content (alpha, bravo, charlie, delta, echo) in a loop to get all value of this array.

How I can do this ?

Thank you

I found the answer :

{% for key,value in array_path %}
    Key : {{ key }}
    Value : {{ value }}
{% endfor %}

There's this example in the SensioLab page on the for tag:

<h1>Members</h1>
<ul>
    {% for key, user in users %}
        <li>{{ key }}: {{ user.username|e }}</li>
    {% endfor %}
</ul>

I guess you want to do the "Iterating over Keys and Values"

As the doc here says, just add "|keys" in the variable you want and it will magically happen.

{% for key, user in users %}
    <li>{{ key }}: {{ user.username|e }}</li>
{% endfor %}

It never hurts to search before asking :)
