column
New in version 2.8: The column filter was added in Twig 2.8.
The column filter returns the values from a single column in the input array.
{% set items = [{ 'fruit' : 'apple'}, {'fruit' : 'orange' }] %}
{% set fruits = items|column('fruit') %}
{# fruits now contains ['apple', 'orange'] #}
Note
Internally, Twig uses the PHP array_column function.
