Serializer context
152+
------------------
153+
154+
The serializer can use a (de)serialization context to control how a resource is (de)serialized.
155+
The context is passed to all normalizers. For example:
156+
157+
*:class:`Symfony\\Component\\Serializer\\Normalizer\\DateTimeNormalizer` uses ``datetime_format`` key as date time format;
158+
*:class:`Symfony\\Component\\Serializer\\Normalizer\\AbstractObjectNormalizer` uses ``empty_iterable_as_object`` to preserve empty objects (keeps ``{}`` instead of ``[]`` in JSON);
159+
160+
..versionadded::5.4
161+
162+
:class:`Symfony\\Component\\Serializer\\Serializer` uses ``empty_arrays_as_object`` to serialize empty array as object (uses ``{}`` instead of ``[]`` in JSON);
163+
164+
You can pass the context like following::
165+
166+
$serializer->serialize($something, 'json', [
167+
DateTimeNormalizer::FORMAT_KEY => 'Y-m-d H:i:s',
168+
]);
169+
170+
$serializer->deserialize($someJson, Something::class, 'json', [
171+
DateTimeNormalizer::FORMAT_KEY => 'Y-m-d H:i:s',
172+
]);
