php - 尝试将数据插入 PDO 但出现错误：重载属性的间接修改无效

Question

我正在使用表单来读取 $_POST 值

$s=new Student();
                $s->Name=$_POST['name'];
                $s->Email=$_POST['email'];
                $s->Education=$_POST['education'];
                $s->Save();

...


public function Save()
    {
        $conn = new PDO('mysql:host=localhost;dbname=week3', 'root', '');
        $statement = $conn->prepare("INSERT INTO user (name, email, education) VALUES (:name,:email,:education)");
        $statement->bindParam(':name', $this->Name);
        $statement->bindParam(':email', $this->Email);
        $statement->bindParam(':education', $this->Education);
        $statement->execute();


    }

我正在使用开关/案例在班级学生中使用 getter 和 setter
