   1 ``split``
   2 =========
   3
   4 .. versionadded:: 1.10.3
   5     The split filter was added in Twig 1.10.3.
   6
   7 The ``split`` filter splits a string by the given delimiter and returns a list
   8 of strings:
   9
  10 .. code-block:: jinja
  11
  12     {{ "one,two,three"|split(',') }}
  13     {# returns ['one', 'two', 'three'] #}
  14
  15 You can also pass a ``limit`` argument:
  16
  17  * If ``limit`` is positive, the returned array will contain a maximum of
  18    limit elements with the last element containing the rest of string;
  19
  20  * If ``limit`` is negative, all components except the last -limit are
  21    returned;
  22
  23  * If ``limit`` is zero, then this is treated as 1.
  24
  25 .. code-block:: jinja
  26
  27     {{ "one,two,three,four,five"|split(',', 3) }}
  28     {# returns ['one', 'two', 'three,four,five'] #}
  29
  30 If the ``delimiter`` is an empty string, then value will be split by equal
  31 chunks. Length is set by the ``limit`` argument (one character by default).
  32
  33 .. code-block:: jinja
  34
  35     {{ "123"|split('') }}
  36     {# returns ['1', '2', '3'] #}
  37
  38     {{ "aabbcc"|split('', 2) }}
  39     {# returns ['aa', 'bb', 'cc'] #}
  40
  41 .. note::
  42
  43     Internally, Twig uses the PHP `explode`_ or `str_split`_ (if delimiter is
  44     empty) functions for string splitting.
