``iterable``
|
|
============
|
|
|
|
``iterable`` checks if a variable is an array or a traversable object:
|
|
|
|
.. code-block:: twig
|
|
|
|
{# evaluates to true if the foo variable is iterable #}
|
|
{% if users is iterable %}
|
|
{% for user in users %}
|
|
Hello {{ user }}!
|
|
{% endfor %}
|
|
{% else %}
|
|
{# users is probably a string #}
|
|
Hello {{ users }}!
|
|
{% endif %}
