Codeigniter Session Refactoring_PHP Tutorial

In order to facilitate the use of PHP session, I have rewritten a simple session method here.

Create new application/libraries/Sessions.php with the following content:

01
02
if (!defined('BASEPATH')) exit('No direct script access allowed');
03

04
/**
05
* Reconstruct the session class
06
* @author chory
07
* @version 1.0
08
* @copyright 2011/6/12
09
*/
10
class Sessions{
11
Private static $instances;
12
Private static function instance()
13
{
14
If (empty(self::$instances)){
15
                @self::$instances = &load_class('session');
16
}
17
          return self::$instances;
18
}
19
Public static function set($key, $value = "")
20
{
21
           self::instance() -> set_userdata(array($key => $value));
22
}
23
Public static function get($key = null)
24
{
25
          if ($key)
26
            {
27
               return self::instance() -> userdata($key);
28
}
29
        else
30
            {
31
                return self::instance() -> all_userdata();
32
}
33
}
34
Public static function _unset($key){
35
          self::instance() -> unset_userdata($key);
36
}
37
Public static function destroy(){
38
           self::instance() -> sess_destroy();
39
}
40
}
Application method:

Sessions::set("username", "admin");

Sessions::get("username");

You can set automatic loading in autoload.php, or manually call Sessions
