Symfony Serializer component: Deserialize array of objects of mixed types

Question

I would like to know if there is a method to deserialize an array containing objects of different types. I built something where I can serialize and deserialize an array of objects of a specific type like this:

$nodes = [
    new PostNode(),
    new PostNode(),
    new PostNode()
];

$serializer = new Serializer( [
    new ObjectNormalizer(),
    new ArrayDenormalizer(),
], [ new JsonEncoder() ] ); 

$data = $serializer->serialize($nodes, 'json');

$deSerializedNodes = $serializer->deserialize( $data, PostNode::class . '[]', 'json' );

我得到的正是插入的数组，所以很好。现在，我想知道是否可以像这样对一个数组进行序列化和反序列化：

$nodes = [
    new PostNode(),
    new PostNode(),
    new PostNode(),
    new FormNode(),
    new FormNode()
];

您只能序列化多个对象类型的数组，如下所示：

$serializer = new Serializer([new GetSetMethodNormalizer(), new ArrayDenormalizer()], [new JsonEncoder()]);

$array = [new Foo('Radhi'), new Bar(26)];

$json = $serializer->serialize($array, 'json');

但是对于反序列化不同对象类型的数组，序列化程序并不清楚，特别是对于具有相同 getter/setter 方法名称的对象，因此我认为您需要针对该特定用例进行一些额外的配置。

检查序列化接口和抽象类以获取更多详细信息。
