Returns a list containing an arithmetic progression of integers:
{% 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):
{% 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
:
{% 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):
{% for i in 0..3 %} {{ i }}, {% endfor %}
Tip
The range
function works as the native PHP range function.
low
: The first value of the sequence.high
: The highest possible value of the sequence.step
: The increment between elements of the sequence.
