Question

是否有办法防止植物检疫中压倒性的财产? 如果是,如何?

Answer 1

The only way to do such a thing is playing with __set() in a class. But, __set is only used for non accessible properties.

对公共财产而言,不认为有办法防止凌驾一切。

Answer 2

我认为这是你想要的:

class A{
    private $a;
    public function __construct(){
        $this->a =  A ;
    }
    public function __get($property){
        return $this->{$property};
    }
}

class B Extends A{
    public function getA(){
        return $this->a;
    }
    public function __get($property){
        return parent::__get($property);
    }
}

$b = new B;
echo $b->getA();

Answer 3

class TheBaseClass {

  private $nomod =  foo ;

  public function getNoMod() {
     return $this->nomod;
  }
}

class TheChildClass extends TheParentClass {
   public function funcUsesNomod(){
      return  The value of nomod is  . $this->getNomod();
   }
}

Answer 4

“Yeah”,如果你能够使其保持不变。见的答复。如何在PHP中实施一个只读的成员变量?,没有ski缩评论。

例:

class user {
  const ALWAYS_ONE = 1;
}

I guess宣布房产为 私人<>/code>,也防止超负荷工作,但也使下层无法使用。
