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