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:

Members
 
     {% for key, user in users %}         
{{ key }}: {{ user.username|e }}
     {% endfor %}

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 %}     
{{ key }}: {{ user.username|e }}
 {% endfor %} 

It never hurts to search before asking :)
