从会话存储文件中读取会话数据 [英] Read the session data from session storage file

问题描述

标题为PHP unserialize()的功能所面对的问题将引发错误.

Facing problem with PHP unserialize() function as titled it is throwing error.

unserialize() [function.unserialize]: Error at offset 0 of 1781 bytes

我还尝试了session_decode()，它返回了bool(false)

I also tried the session_decode() which return bool(false)

magic_quotes_gpc是Off.

好吧，我正在读取已序列化的文件的内容.文件内容如下所示.

Well, I am reading content of file which is serialized. File contents looks like below.

我的PHP代码在下面

$file='/var/www/html/products/var/session/sess_0ehb7ek0hmunqo3kq70t0t6mb0';
$contents=file_get_contents($file);
$data = unserialize($contents); 
var_dump($data);

在反序列化数据之前，我已经尝试过stripslashes(). 不确定数据中的问题在哪里. 我无法更改将数据存储到文件中的机制，因为这是由Magento处理的，用于在文件级别管理会话.

I already tried the stripslashes() before unserializing data. Not sure where is the problem in data. I can not change the mechanism of storing data in to file because this is handled by Magento for mananging session on File level.

推荐答案

如果要解码会话数据，请使用session_decode(请参见

If you want to decode session data, use session_decode (see the manual). unserialize only decodes single variables, not session data.

您可以执行以下操作:

$file = '/var/www/html/products/var/session/sess_ciktos8icvk11grtpkj3u610o3';
$contents = file_get_contents($file);
session_start();
session_decode($contents);
print_r($_SESSION);
