使用Symfony序列化程序将JSON反序列化为类实例数组

composer require symfony/serializer

class Person
{
    private $name;
    private $age;

    public function getName()
    {
        return $this->name;
    }

    public function getAge()
    {
        return $this->age;
    }
}

use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Encoder\JsonEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;

// 创建一个JsonEncoder实例
$encoder = new JsonEncoder();

// 创建一个ObjectNormalizer实例
$normalizer = new ObjectNormalizer();

// 创建一个Serializer实例，将编码器和规范化器传递给它
$serializer = new Serializer([$normalizer], [$encoder]);

// 将JSON字符串反序列化为Person类实例数组
$json = '{"persons":[{"name":"John","age":30},{"name":"Jane","age":25}]}';
$persons = $serializer->deserialize($json, 'App\Entity\Person[]', 'json');

// 打印类实例数组中的每个实例的姓名和年龄
foreach ($persons as $person) {
    echo 'Name: ' . $person->getName() . ', Age: ' . $person->getAge() . "\n";
}

{
  "persons": [
    {
      "name": "John",
      "age": 30
    },
    {
      "name": "Jane",
      "age": 25
    }
  ]
}
