PHP 序列化与反序列化

<?php
class Stu{
    public $name;
    public $sex;
    public function intro(){
        print_r($this->name."--".$this->sex);        
    }
} 

$one = new Stu();
$one->name = "chenbin";
$one->sex = "man";
//$one->intro();

/*print_r((array)$one);
var_dump($one);*/

$str = serialize($one);
file_put_contents("one.txt", $str);
//反序列化
$str = file_get_contents(‘one.txt‘);
$one = unserialize($str);
echo $one->name;

$arr = $arrayName = array(‘a‘ => 1,‘b‘=>2 );
$str = serialize($arr);
file_put_contents(‘one.txt‘, $str);
$str = file_get_contents(‘one.txt‘);
$str = unserialize($str);
print_r($str);
