``url_encode``
==============
.. versionadded:: 1.12.3
Support for encoding an array as query string was added in Twig 1.12.3.
The ``url_encode`` filter percent encodes a given string as URL segment
or an array as query string:
.. code-block:: jinja
{{ "path-seg*ment"|url_encode }}
{# outputs "path-seg%2Ament" #}
{{ "string with spaces"|url_encode(true) }}
{# outputs "string%20with%20spaces" #}
{{ {'param': 'value', 'foo': 'bar'}|url_encode }}
{# outputs "param=value&foo=bar" #}
.. note::
Internally, Twig uses the PHP `urlencode`_ (or `rawurlencode`_ if you pass
``true`` as the first parameter) or the `http_build_query`_ function.
.. _`urlencode`: http://php.net/urlencode
.. _`rawurlencode`: http://php.net/rawurlencode
.. _`http_build_query`: http://php.net/http_build_query
