use Symfony\Component\Serializer\Mapping\Loader\AnnotationLoader;

use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Serializer;
require_once './vendor/autoload.php';
class InnerModel
{
/** @var string */
public $id;
}
class Model
{
/** @var ArrayCollection<InnerModel> */
public $items;
}
$serializer = new Serializer([
new ObjectNormalizer(
new ClassMetadataFactory(
new AnnotationLoader()
),
null,
null,
new PhpDocExtractor()
),
new ArrayDenormalizer(),
], ['json' => new JsonEncoder()]);
$data = $serializer->deserialize(
'{"items":[{"id": "1"}]}',
Model::class,
'json',
[
'allow_extra_attributes' => true
]
);
var_dump($data);Actual result
class Model#32 (1) {

}
}
}

class Model#30 (1) {
public $items =>

class InnerModel#62 (1) {
...
