+
.. _`strtotime`: http://www.php.net/strtotime
.. _`DateTime`: http://www.php.net/DateTime
Read the documentation for the :doc:`defined<../tests/defined>` and
:doc:`empty<../tests/empty>` tests to learn more about their semantics.
+
+Arguments
+---------

{{ var|escape(strategy)|raw }} {# won't be double-escaped #}
{% endautoescape %}
+Arguments
+---------
+
+ * ``strategy``: The escaping strategy
+ * ``charset``: The string charset
+
.. _`htmlspecialchars`: http://php.net/htmlspecialchars
{{ [1, 2, 3]|join('|') }}
{# returns 1|2|3 #}
+
+Arguments
+---------
+
+ * ``glue``: The separator
Internally, Twig uses the PHP `json_encode`_ function.
+Arguments
+---------
+
+ * ``options``: The options
+
.. _`json_encode`: http://php.net/json_encode
The defaults set for ``number_format`` can be over-ridden upon each call using the
additional parameters.
+Arguments
+---------
+
+ * ``decimal``: The number of decimal points to display
+ * ``decimal_point``: The character(s) to use for the decimal point
+ * ``decimal_sep``: The character(s) to use for the thousands separator
+
.. _`number_format`: http://php.net/number_format
{# returns I like foo and bar
if the foo parameter equals to the foo string. #}
+Arguments
+---------
+
+ * ``replace_pairs``: The placeholder values
+
.. seealso:: :doc:`format<format>`
It also works with objects implementing the `Traversable`_ interface.
+Arguments
+---------
+
+ * ``start``: The start of the slice
+ * ``length``: The size of the slice
+ * ``preserve_keys``: Whether to preserve key or not (when the input is an array)
+
.. _`Traversable`: http://php.net/manual/en/class.traversable.php
.. _`array_slice`: http://php.net/array_slice
.. _`substr`: http://php.net/substr
Internally, Twig uses the PHP `explode`_ or `str_split`_ (if delimiter is
empty) functions for string splitting.
+Arguments
+---------
+
+ * ``delimiter``: The delimiter
+ * ``limit``: The limit argument
+
.. _`explode`: http://php.net/explode
.. _`str_split`: http://php.net/str_split
Internally, Twig uses the PHP `trim`_ function.
+Arguments
+---------
+
+ * ``character_mask``: The characters to strip
+
.. _`trim`: http://php.net/trim
{% for i in 0..10 %}
{{ cycle(fruits, i) }}
{% endfor %}
+
+Arguments
+---------
+
+ * ``position``: The cycle position
$twig = new Twig_Environment($loader);
$twig->getExtension('core')->setTimezone('Europe/Paris');
+Arguments
+---------
+
+ * ``date``: The date
+ * ``timezone``: The timezone
+
.. _`date`: http://www.php.net/date
Internally, Twig uses the PHP `var_dump`_ function.
+Arguments
+---------
+
+ * ``context``: The context to dump
+
.. _`XDebug`: http://xdebug.org/docs/display
.. _`var_dump`: http://php.net/var_dump
{{ random() }} {# example output: 15386094 (works as native PHP `mt_rand`_ function) #}
{{ random(5) }} {# example output: 3 #}
+Arguments
+---------
+
+ * ``values``: The values
+
.. _`mt_rand`: http://php.net/mt_rand
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.
+
.. _`range`: http://php.net/range
Even if you will probably always use the ``template_from_string`` function
with the ``include`` tag, you can use it with any tag or function that
takes a template as an argument (like the ``embed`` or ``extends`` tags).
+
+Arguments
+---------
+
+ * ``template``: The template
Go to the :doc:`functions<functions/index>` page to learn more about the
built-in functions.
+Named Arguments
+---------------
+
+.. versionadded:: 1.12
+ Support for named arguments was added in Twig 1.12.
+
+Arguments for filters and functions can also be passed as *named arguments*:
+
+.. code-block:: jinja
+
+ {% for i in range(low=1, high=10, step=2) %}
+ {{ i }},
+ {% endfor %}
+
+Using named arguments makes your templates more explicit about the meaning of
+the values you pass as arguments:
+
+.. code-block:: jinja
+
+ {{ data|convert_encoding('UTF-8', 'iso-2022-jp') }}
+
+ {# versus #}
+
+ {{ data|convert_encoding(from='iso-2022-jp', to='UTF-8') }}
+
+Named arguments also allow you to skip some arguments for which you don't want
+to change the default value::
+
+.. code-block:: jinja
+
+ {# the first argument is the date format, which defaults to the global date format if null is passed #}
+ {{ "now"|date(null, "Europe/Paris") }}
+
+ {# or skip the format value by using a named argument for the timezone #}
+ {{ "now"|date(timezone="Europe/Paris") }}
+
+You can also use both positional and named arguments in one call, which is not
+recommended as it can be confusing:
+
+.. code-block:: jinja
+
+ {# both work #}
+ {{ "now"|date('d/m/Y H:i', timezone="Europe/Paris") }}
+ {{ "now"|date(timezone="Europe/Paris", 'd/m/Y H:i') }}
+
+.. tip::
+
+ Each function and filter documentation page has a section where the names
+ of all arguments are listed when supported.
+
