如何创建不允许动态属性的 PHP类？

class User
{
  public $username;
  public $password;
}

$user = new User;
$user->username = "bill.gates";

// This is a dynamic property and I need setting it to be considered illegal.
$user->something = 123;

解决方法

Magic methods救援：

class User
{
  public $username;
  public $password;

  public function __set($key,$value) {
    throw new Exception('illegal'); // or just trigger_error()
  }
}
