浅谈PHP拦截器之__set()与__get()的理解与使用方法

<?php//拦截器的使用class Computer{private $name;private $price;private $cpu;private $clocked;//拦截器之赋值public function __set($key,$value){//那么：$key=name $value="联想" 则有： $this->name="联想"return $this->$key=$value;}//拦截器之取值public function __get($key){if (isset($key)){//那么： $key=name 则$this->name 所以自然就return了"联想"return $this->$key;}else {return NULL;}}}//正是因为的拦截器存在，才能如此用$computer=new Computer();$computer->name="联想";$computer->price=5600;$computer->cpu="八核";$computer->clocked="1600hz";echo $computer->name;echo $computer->price;echo $computer->cpu;echo $computer->clocked;
