php怎么传输object_php对象序列化传输方法

class User {
    public $name;
    public $age;

    public function __construct($name, $age) {
        $this->name = $name;
        $this->age = $age;
    }

    public function getInfo() {
        return "姓名：{$this->name}，年龄：{$this->age}";
    }
}

// 创建对象
$user = new User("张三", 25);

// 序列化对象
$serialized = serialize($user);
echo $serialized; // 输出类似：O:4:"User":2:{s:4:"name";s:6:"张三";s:3:"age";i:25;}

// 假设通过POST、session或文件等方式传输$serialized

// 接收并反序列化
$restoredUser = unserialize($serialized);
echo $restoredUser->getInfo(); // 输出：姓名：张三，年龄：25

class User implements JsonSerializable {
    public $name;
    public $age;

    public function __construct($name, $age) {
        $this->name = $name;
        $this->age = $age;
    }

    public function jsonSerialize() {
        return [
            'name' => $this->name,
            'age' => $this->age
        ];
    }

    public function getInfo() {
        return "姓名：{$this->name}，年龄：{$this->age}";
    }
}

$user = new User("李四", 30);

// 转为JSON字符串传输
$jsonString = json_encode($user);
echo $jsonString; // 输出：{"name":"李四","age":30}

// 接收后解析为stdClass对象或重建User实例
$data = json_decode($jsonString);
$restoredUser = new User($data->name, $data->age);
echo $restoredUser->getInfo();

session_start();
$_SESSION['user'] = serialize($user); // 存储

// 另一个页面
session_start();
$user = unserialize($_SESSION['user']);
