如何在Laravel雄辯模型中創建私有財產？

Question

似乎是太明顯，但如何使一個類私有財產：

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) 

這是Laravel 5.1

儘量覆蓋__get(){}和__set(){}魔術方法，所以這將是類似的東西：

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'); 
     } 
    } 
}
