By default, it converts them to strings using the `RFC3339`_ format. - To convert the objects to integers or floats, set the serializer context option - ``DateTimeNormalizer::CAST_KEY`` to ``int`` or ``float``. - - .. versionadded:: 7.1 - - The ``DateTimeNormalizer::CAST_KEY`` context option was introduced in Symfony 7.1. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\DateTimeZoneNormalizer` - This normalizer converts :phpclass:`DateTimeZone` objects into strings that - represent the name of the timezone according to the `list of PHP timezones`_. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\DataUriNormalizer` - This normalizer converts :phpclass:`SplFileInfo` objects into a `data URI`_ - string (``data:...``) such that files can be embedded into serialized data. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\DateIntervalNormalizer` - This normalizer converts :phpclass:`DateInterval` objects into strings. - By default, it uses the ``P%yY%mM%dDT%hH%iM%sS`` format. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\BackedEnumNormalizer` - This normalizer converts a \BackedEnum objects into strings or integers. - - By default, an exception is thrown when data is not a valid backed enumeration. If you - want ``null`` instead, you can set the ``BackedEnumNormalizer::ALLOW_INVALID_VALUES`` option. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\FormErrorNormalizer` - This normalizer works with classes that implement - :class:`Symfony\\Component\\Form\\FormInterface`. - - It will get errors from the form and normalize them into a normalized array. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\ConstraintViolationListNormalizer` - This normalizer converts objects that implement - :class:`Symfony\\Component\\Validator\\ConstraintViolationListInterface` - into a list of errors according to the `RFC 7807`_ standard. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\ProblemNormalizer` - Normalizes errors according to the API Problem spec `RFC 7807`_. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\CustomNormalizer` - Normalizes a PHP object using an object that implements :class:`Symfony\\Component\\Serializer\\Normalizer\\NormalizableInterface`. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\UidNormalizer` - This normalizer converts objects that extend - :class:`Symfony\\Component\\Uid\\AbstractUid` into strings. - The default normalization format for objects that implement :class:`Symfony\\Component\\Uid\\Uuid` - is the `RFC 4122`_ format (example: ``d9e7a184-5d5b-11ea-a62a-3499710062d0``). - The default normalization format for objects that implement :class:`Symfony\\Component\\Uid\\Ulid` - is the Base 32 format (example: ``01E439TP9XJZ9RPFH3T1PYBCR8``). - You can change the string format by setting the serializer context option - ``UidNormalizer::NORMALIZATION_FORMAT_KEY`` to ``UidNormalizer::NORMALIZATION_FORMAT_BASE_58``, - ``UidNormalizer::NORMALIZATION_FORMAT_BASE_32`` or ``UidNormalizer::NORMALIZATION_FORMAT_RFC_4122``. - - Also it can denormalize ``uuid`` or ``ulid`` strings to :class:`Symfony\\Component\\Uid\\Uuid` - or :class:`Symfony\\Component\\Uid\\Ulid`. The format does not matter. - -:class:`Symfony\\Component\\Serializer\\Normalizer\\TranslatableNormalizer` - This normalizer converts objects that implement - :class:`Symfony\\Contracts\\Translation\\TranslatableInterface` into - translated strings, using the - :method:`Symfony\\Contracts\\Translation\\TranslatableInterface::trans` - method. You can define the locale to use to translate the object by - setting the ``TranslatableNormalizer::NORMALIZATION_LOCALE_KEY`` serializer - context option. - -.. note:: - - You can also create your own Normalizer to use another structure.
