716+ During Deserialization
717+ ~~~~~~~~~~~~~~~~~~~~~~
718+
719+ PHP considers many different values as true or false. For example, the
720+ strings ``true ``, ``1 ``, and ``yes `` are considered true, while
721+ ``false ``, ``0 ``, and ``no `` are considered false.
722+
723+ When deserializing, the Serializer component can take care of this
724+ automatically. This can be done by using the ``AbstractNormalizer::FILTER_BOOL ``
725+ context option::
726+
727+ use Acme\Person;
728+ use Symfony\Component\Serializer\Normalizer\AbstractNormalizer;
729+ use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
730+ use Symfony\Component\Serializer\Serializer;
731+
732+ $normalizer = new ObjectNormalizer();
733+ $serializer = new Serializer([$normalizer]);
734+
735+ $data = $serializer->denormalize(['sportsperson' => 'yes'], Person::class, context: [AbstractNormalizer::FILTER_BOOL => true]);
736+
737+ This context makes the deserialization process behave like the
738+ :phpfunction: `filter_var ` function with the ``FILTER_VALIDATE_BOOL `` flag.
