`reverse`

The reverse filter reverses a sequence, a mapping, or a string:

        1
2
3
4
5
6
7
        {% for user in users|reverse %}
    ...
{% endfor %}

{{ '1234'|reverse }}

{# outputs 4321 #}
    

Tip

For sequences and mappings, numeric keys are not preserved. To reverse them as well, pass true as an argument to the reverse filter:

        1
2
3
4
5
6
7
8
9
10
11
        {% for key, value in {1: "a", 2: "b", 3: "c"}|reverse %}
    {{ key }}: {{ value }}
{%- endfor %}

{# output: 0: c    1: b    2: a #}

{% for key, value in {1: "a", 2: "b", 3: "c"}|reverse(true) %}
    {{ key }}: {{ value }}
{%- endfor %}

{# output: 3: c    2: b    1: a #}
    

Note

It also works with objects implementing the Traversable interface.
