Yii-session管理

一，组件注册

   CWebApplication::registerCoreComponents()

protected function registerCoreComponents()
{
    parent::registerCoreComponents();
        $components=array(
        ‘session‘=>array(
        ‘class‘=>‘CHttpSession‘,
        ), 
            //...
        );
        $this->setComponents($components);
}

二，使用

//session操作
$se = Yii::app()->session;       //获得组件
//设置
$se[‘test‘]=‘my vlaue‘;         //组件
$_SESSION[‘11‘] = ‘1111111111‘; //常规
//获取
echo ‘test:`‘.$se[‘test‘].‘`‘;
echo ‘11:`‘.$_SESSION[‘11‘].‘`‘;
//删除
$se->remove(‘11‘);               //组件
unset($se[‘test‘]);             //常规
//获取全部
$test_sessions = $se->toArray();//组件
$test_sessions = $_SESSION;     //常规
print_r($test_sessions);exit();

三，源码

public function get($key,$defaultValue=null)
{
    return isset($_SESSION[$key]) ? $_SESSION[$key] :         $defaultValue;
}
    public function remove($key)
{
    if(isset($_SESSION[$key]))
    {
        $value=$_SESSION[$key];
        unset($_SESSION[$key]);
        return $value;
    }
    else
        return null;
}
    public function offsetGet($offset)
{
    return isset($_SESSION[$offset]) ? $_SESSION[$offset] : null;
}
    public function offsetSet($offset,$item)
{
    $_SESSION[$offset]=$item;
}
    public function toArray()
{
    return $_SESSION;
}
    public function destroy()
{
    if(session_id()!==‘‘)
    {
        @session_unset();
        @session_destroy();
    }
}
