unserialize(),serialize(),__wakeup(),__sleep()函数

基于序列化与反序列化，在此我只是举一个例子，For example:

class student{    private $name;    private $age;    private $address;    public function __construct($name,$age,$address){        $this->name=$name;        $this->age=$age;        $this->address=$address;       }    public function information(){        echo "My name:".$this->name.";My age:".$this->age."My address:".$this->address;    }}$P=new student("小明"，"25","湖北");$P->information();

output: My name:小明;My age:25;My address:湖北;

For example:

class student{    private $name;    private $age;    private $address;    public function __construct($name,$age,$address){        $this->name=$name;        $this->age=$age;        $this->address=$address;       }    public function __sleep(){        $arr=array("name","age");        return ($arr);    }    public function __walkup(){        $this->age=30;    }    public function information(){        echo "My name:".$this->name.";My age:".$this->age."My address:".$this->address;    }}$P=new student("小红",30,"湖南");$P->information();echo "<br>";$String=serialize($P);echo $String;echo "<br>";$String2=unserialize($String);$String2->information();

output:

My name:小红;My age:30My address:湖南O:7:"student":2:{s:13:"studentname";s:6:"小红";s:12:"studentage";i:30;}My name:小红;My age:30My address:
