PHP Session Functions

The following is a simple wrapper class to work with PHP sessions.

*You need to call session_start(); on every page you need session acccess. Maybe the following could be added to this class to ensure the session is started.

if(!isset($_SESSION))
{
     session_start();
}

copy
<?php
namespace Common;

class Session
{

    public static function Clear()
    {
        if(!isset($_SESSION))
        {
            session_destroy();
        }
    }


    public static function GetValue($key, $default = null)
    {        
        $key = strtolower($key);

        if (isset($_SESSION[$key]))
        {
            return $_SESSION[$key];
        }

        return $default;
    }


    public static function SetValue($key, $value)
    {        
        $key = strtolower($key);

        //print_r($_SESSION);
        $_SESSION[$key] = $value;
    }
}

?>
