New in version 1.10.3: The split filter was added in Twig 1.10.3.
The split filter splits a string by the given delimiter and returns a list of strings:
{% 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.
{% 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).
{% 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.
