使用datetime对象symfony php对Json进行编码/解码

composer require symfony/serializer

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

// 创建一个Serializer实例
$serializer = new Serializer([new ObjectNormalizer()], [new JsonEncoder()]);

// 创建一个datetime对象
$datetime = new \DateTime();

// 将datetime对象编码为JSON字符串
$json = $serializer->serialize($datetime, 'json');

// 打印编码后的JSON字符串
echo $json;

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

// 创建一个Serializer实例
$serializer = new Serializer([new ObjectNormalizer()], [new JsonEncoder()]);

// JSON字符串
$json = '{"date":"2022-01-01 12:00:00","timezone_type":3,"timezone":"Asia/Shanghai"}';

// 将JSON字符串解码为datetime对象
$datetime = $serializer->deserialize($json, \DateTime::class, 'json');

// 打印解码后的datetime对象
var_dump($datetime);
