range¶
Returns a list containing an arithmetic progression of integers:
1 2 3 4 5 | {% for i in range(0, 3) %}
{{ i }},
{% endfor %}
{# outputs 0, 1, 2, 3, #}
|
When step is given (as the third parameter), it specifies the increment (or decrement for negative values):
1 2 3 4 5 | {% for i in range(0, 6, 2) %}
{{ i }},
{% endfor %}
{# outputs 0, 2, 4, 6, #}
|
Note
Note that if the start is greater than the end, range assumes a step of
-1:
1 2 3 4 5 | {% for i in range(3, 0) %}
{{ i }},
{% endfor %}
{# outputs 3, 2, 1, 0, #}
|
The Twig built-in .. operator is just syntactic sugar for the range
function (with a step of 1, or -1 if the start is greater than the end):
1 2 3 | {% for i in 0..3 %}
{{ i }},
{% endfor %}
|
Tip
The range function works as the native PHP range function.
Arguments¶
low: The first value of the sequence.high: The highest possible value of the sequence.step: The increment between elements of the sequence.
