``json_encode``
===============

The ``json_encode`` filter returns the JSON representation of a value:

.. code-block:: twig

    {{ data|json_encode() }}

.. note::

    Internally, Twig uses the PHP `json_encode`_ function.

Arguments
---------

* ``options``: A bitmask of `json_encode options`_: ``{{
  data|json_encode(constant('JSON_PRETTY_PRINT')) }}``.
  Combine constants using :ref:`bitwise operators<template_logic>`:
  ``{{ data|json_encode(constant('JSON_PRETTY_PRINT') b-or constant('JSON_HEX_QUOT')) }}``
