trim

The trim filter strips whitespace (or other characters) from the beginning and end of a string:

.. code-block:: twig

{{ '  I like Twig.  '|trim }}

{# outputs 'I like Twig.' #}

{{ '  I like Twig.'|trim('.') }}

{# outputs '  I like Twig' #}

{{ '  I like Twig.  '|trim(side: 'left') }}

{# outputs 'I like Twig.  ' #}

{{ '  I like Twig.  '|trim(' ', 'right') }}

{# outputs '  I like Twig.' #}

.. note::

Internally, Twig uses the PHP `trim`_, `ltrim`_, and `rtrim`_ functions.

Arguments

• character_mask: The characters to strip

• side: The default is to strip from the left and the right (both) sides, but left and right will strip from either the left side or right side only
