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

<?php
class Person{
    private $name;
    private $age;
    private $sex;

    public function __construct($name, $age, $sex){
        $this->name = $name;
        $this->age = $age;
        $this->sex = $sex;
    }

    public function getname(){
        return $this->name;
    }
    public function getage(){
        return $this->age;
    }
    public function getsex(){
        return $this->sex;
    }
}

$personOne = new Person('weixing', '21', 'M');
$personBefore = serialize($personOne);   //产生一个序列化的字符串
//O:6:"Person":3:{s:12:"Personname";s:7:"weixing";s:11:"Personage";s:2:"21";s:11:"Personsex";s:1:"M";}
$personAfter = unserialize($personBefore);  //转换为PHP的值，相当于$personOne
print_r($personOne);
echo "<br/>";
print_r($personBefore);
echo "<br/>";
print_r($personAfter);
?>
