PHP中的serialize()和unserialize()

serialize — 产生一个可存储的值的表示

unserialize — 从已存储的表示中创建 PHP 的值

 1 <?php
 2 class Person{
 3     private $name;
 4     private $age;
 5     private $sex;
 6 
 7     public function __construct($name, $age, $sex){
 8         $this->name = $name;
 9         $this->age = $age;
10         $this->sex = $sex;
11     }
12 
13     public function getname(){
14         return $this->name;
15     }
16     public function getage(){
17         return $this->age;
18     }
19     public function getsex(){
20         return $this->sex;
21     }
22 }
23 
24 $personOne = new Person('weixing', '21', 'M');
25 $personBefore = serialize($personOne);   //产生一个序列化的字符串
26 //O:6:"Person":3:{s:12:"Personname";s:7:"weixing";s:11:"Personage";s:2:"21";s:11:"Personsex";s:1:"M";}
27 $personAfter = unserialize($personBefore);  //转换为PHP的值，相当于$personOne
28 print_r($personOne);
29 echo "<br/>";
30 print_r($personBefore);
31 echo "<br/>";
32 print_r($personAfter);
33 ?>
