我应该codeIgniter使用哪个会话库？ [英] Which session library should I use with CodeIgniter?

问题描述

我最近开始使用CI与它CI会话，但我注意到一个特别的一点是耗费更多的时间做与CI的会话比基本PHP会话：阵列的。

I have recently started using CI and with it CI sessions, but I have noticed that one thing in particular is much more time consuming to do with CI sessions than with the base PHP sessions: Arrays.

我有数据的数组仍然存在，无论所谓的登录/注销 $ _ SESSION ['统计'] ，然后我在表单数组中存储数据：

I have an array of data that persists regardless of login/logout called $_SESSION['stats'], I then store data in that array in the form:

$ _ SESSION ['统计'] ['last_page'] = $ _ SERVER ['REQUEST_URI']; 。

而当用户注销时，它保存在一个变量的统计数组，清除会话，然后加载它放回了新的会话。

And when a user logs out, it saves the stats array in a variable, clears the session, and then loads it back into the new session.

的问题是，为了编辑last_page键，上述代替一行，我必须使用此code：

The problem is that in order to edit the last_page key, instead of the one line above, I have to use this code:

$stats = $this->CI->session->userdata('stats');
$stats['last_page'] = $_SERVER["REQUEST_URI"];
$this->CI->session->set_userdata('stats', $stats);

这是一些烦恼我在CI会发现，这使我感到不满意的地方作为我的会话处理程序之一。所以我的问题是：我应该用codeIgniter使用哪个会话系统的...是有一些原因使用CI会议？是否有一个CI库，你有什么建议？为什么不使用PHP会议？

This is one of a number of annoyances I find in CI sessions, which cause me to feel dissatisfied with it as my session handler. So my question is: Which session system should I use with CodeIgniter?... is there some reason for using CI sessions? Is there a CI library that you would suggest? Why not just use PHP sessions?

谢谢，

推荐答案

CI会议提供了一些额外的功能; 如自动重新生成会话ID每一个时间给量（安全性），IP地址跟踪和 flashdata 的（它读取一次之后的清除会话数据）。

CI sessions offers some extra functionality; such as auto regenerating the session id every given amount of time (for security), IP address tracking, and flashdata (session data that's cleared after it's read once).

CI的会话机制店在cookie中的所有数据。 PHP的本地会话机制是存储服务器端。每个人都有它的优势/劣势。 Cookies只能存储4KB的数据，因此，如果您存储大量的会话PHP自身的会话数据，可能会更好。

CI's session mechanism stores all the data in a cookie. PHP's native session mechanism is stored server side. Each have it's advantages/disadvantages. Cookies can only hold 4KB of data, so if your storing large amounts of data in session PHP native sessions might be better.

如果您决定要使用本机PHP会话使用： 会话混合（CI 1.7.2）

If you decide to you want to use native PHP sessions use: Session Hybrid (CI 1.7.2)

会话Hybrid采用原生PHP会话，可以存储在默认CI DB会话数据，是一个简易替换为CI的会话类，只需要一个文件被改写。

Session Hybrid uses native PHP sessions, can store session data in the default CI db, is a drop-in replacement for CI’s session class, and only requires one file to be rewritten.

[*如果使用CI版本的前的1.7.0尝试 PHPSession 并本地会话]

[* If using a CI version before 1.7.0 try PHPSession and Native Session]

附注：如果你选择留在CI的会议，额外的安全性，你可以存储在数据库中的会话和加密的cookies（见的Session preferences ）。

Side note: If you choose to stay with CI's sessions, for additional security you can store sessions in a database and encrypt the cookies (see Session Preferences).
