php - 如何在 Laravel Eloquent 模型中将属性设为私有(private)？

Question

似乎太明显了，但我如何将类属性设为私有(private):

class User extends Model
{
   private $name; // or protected

}

$user = new User();
$user->name = "Mrs. Miggins";     // <- I want this to generate an error
echo $user->name; // Mrs. Miggins, (this too)

这是 Laravel 5.1

尝试覆盖 __get(){} 和 __set(){} 魔法方法，所以它会是这样的:

class User extends Model
{
  protected $privateProperties = ['name'];

  public function __get($varName) {
      $this->isPrivate($varName);

      return parent::__get($varName);
  }

  public function __set($varName, $value) {
      $this->isPrivate($varName);

      return parent::__set($varName, $value);
  }

  protected function isPrivate($varName) {
      if (in_array($varName, $this->privateProperties)) {
          throw new \Exception('The ' . $varName. ' property is private');
      }
  }
}
