php 序列化与反序列化

 <?php

 //声明一个类

 class dog {

     var $name;

     var $age;

     var $owner;

     function dog($in_name="unnamed",$in_age="",$in_owner="unknown") {

         $this->name = $in_name;

         $this->age = $in_age;

         $this->owner = $in_owner;

     }

     function getage() {

         return ($this->age * );

     }

     function getowner() {

         return ($this->owner);

     }

     function getname() {

         return ($this->name);

     }

 }

 //实例化这个类

 $ourfirstdog = new dog("Rover",,"Lisa and Graham");

 //用serialize函数将这个实例转化为一个序列化的字符串

 $dogdisc = serialize($ourfirstdog);

 print $dogdisc; //$ourfirstdog 已经序列化为字符串 O:3:"dog":3:{s:4:"name";s:5:"Rover";s:3:"age";i:12;s:5:"owner";s:15:"Lisa and Graham";}
