PHP的serialize与json_encode

对比

JSON优势：变量序列化后依然可读,可以给其他系统使用，因为JSON格式是标准的
JSON劣势：
只对UFT-8的数据有效，其他编码可能不能很好工作
只对stdClass类的示例有效,对于私有属性会忽略

Serialize优势：允许非UTF-8的变量 ，支持除了stdClass 示例外的其他实例
Serialize劣势：编码后的文本对人来说是不可读的,无法被其他语言的系统引用

代码 

$web = new stdClass;
$web->site = 'tantengvip';
$web->owner = 'tuntun';
$web->age = 5;
//和
$web = array();
$web['site'] = 'tantengvip';
$web['owner'] = 'tuntun';
$web['age'] = 5;

var_dump(serialize($web));
var_dump(unserialize(serialize($web)));
var_dump(json_encode($web));
var_dump(json_decode(json_encode($web)));
