php 序列化与反序列化

 1 <?php

 2 //声明一个类

 3 class dog {

 4 

 5     var $name;

 6     var $age;

 7     var $owner;

 9     function dog($in_name="unnamed",$in_age="0",$in_owner="unknown") {

10         $this->name = $in_name;

11         $this->age = $in_age;

12         $this->owner = $in_owner;

13     }

15     function getage() {

16         return ($this->age * 365);

19     function getowner() {

20         return ($this->owner);

21     }

22     

23     function getname() {

24         return ($this->name);

25     }

26 }

27 //实例化这个类

28 $ourfirstdog = new dog("Rover",12,"Lisa and Graham");

29 //用serialize函数将这个实例转化为一个序列化的字符串

30 $dogdisc = serialize($ourfirstdog);

31 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";}
