Zend_Session:反序列化会话数据 [英] Zend_Session: unserialize session data

问题描述

我正在使用会话 SaveHandler 将会话数据保存在数据库中.

I'm using session SaveHandler to persist session data in the database.

来自数据库的示例 session_data 列:

Sample session_data column from the database:

Messenger|a:1:{s:13:"page_messages";a:0:{}}userSession|a:1:{s:7:"referer";s:32:"http://cms.dev/user/profile/view";}Zend_Auth|a:1:{s:7:"storage";O:19:"User_Model_Identity":3:{s:2:"id";s:1:"1";s:8:"username";s:13:"administrator";s:4:"slug";s:13:"administrator";}}

我想从这个会话数据中删除 Zend_Auth 对象.

I want to delete Zend_Auth object from this session data.

如何反序列化这些对象并删除我需要的对象?

How can I unserialize those objects and remove object I need?

我怀疑，我不必编写自定义解析器，Zend_Session 已经有一种方法可以做到这一点.我尝试了 unserialize 的不同组合，但它仍然返回 false.

I suspect, that I don't have to write my custom parser, that Zend_Session already has a method to do this. I have tried different combinations of unserialize but it still returns false.

我使用的是 ZF 1.10.2 和 Doctrine 1.2 中的自动加载器

I'm using autoloader from ZF 1.10.2 and Doctrine 1.2

推荐答案

下面的代码可以工作，它不是我的，但本质上它的作用是使用管道作为分隔符将会话字符串分开，反序列化单独分割块.

The code below will work, it is not mine, but in essence what it does is split the session string apart using the pipe as a delimiter, the unserialize the split chunks individually.

问题是php中unserialize函数的构建不理解串联的序列化.

The problem is that the build in unserialize function in php doesn't understand the concatenated serialization.

function unserialize_session_data( $serialized_string ) {
   $variables = array();
   $a = preg_split("/(\w+)\|/", $serialized_string, -1, PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE);
   for($i=0;$i<count($a);$i=$i+2){
       $variables[$a[$i]] = unserialize($a[$i+1]);
   }
   return($variables);
}
