``range``
|
|
=========
|
|
|
|
Returns a list containing an arithmetic progression of integers:
|
|
|
|
.. code-block:: twig
|
|
|
|
{% 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):
|
|
|
|
.. code-block:: twig
|
|
|
|
{% 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``:
|
|
|
|
.. code-block:: twig
|
|
|
|
{% 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):
|
|
|
|
.. code-block:: twig
|
|
|
|
{% 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.
