``split``
=========
The ``split`` filter splits a string by the given delimiter and returns a list
of strings:
.. code-block:: twig
{% set foo = "one,two,three"|split(',') %}
{# foo contains ['one', 'two', 'three'] #}
You can also pass a ``limit`` argument:
* If ``limit`` is positive, the returned array will contain a maximum of
limit elements with the last element containing the rest of string;
* If ``limit`` is negative, all components except the last -limit are
returned;
* If ``limit`` is zero, then this is treated as 1.
.. code-block:: twig
{% set foo = "one,two,three,four,five"|split(',', 3) %}
{# foo contains ['one', 'two', 'three,four,five'] #}
If the ``delimiter`` is an empty string, then value will be split by equal
chunks. Length is set by the ``limit`` argument (one character by default).
.. code-block:: twig
{% set foo = "123"|split('') %}
{# foo contains ['1', '2', '3'] #}
{% set bar = "aabbcc"|split('', 2) %}
{# bar contains ['aa', 'bb', 'cc'] #}
.. note::
Internally, Twig uses the PHP `explode`_ or `str_split`_ (if delimiter is
empty) functions for string splitting.
