php model与json_encode/json_decode

常用于model的操作，看看就知道了

<?php 

class UserModel
{
    var  $user_id = 0;
    var  $user_name = '';
    var  $user_email = '';
    var  $user_pwd = '';

    function UserModel()
    {

    }
}

?>

使用json_encode将Model序列化为json

$md->user_id = '3';
$md->user_name = 'Lee';
$md->user_email = "928532756@qq.com";
$md->user_pwd = "";

$json = json_encode($md) 

exit($json);   

使用json_decode将json反序列化为model

$md = json_decode($json);

var_dump($md);
