How to set up session in yii

First of all, in the Yii framework, you do not need to use session_start() like standard PHP code. In the Yii framework, the autoStart attribute is set to true by default, so even if session_start() is not used, you can still use $_SESSION global variable, but it is best to use Yii::app->session:

## encapsulated by the Yii framework to set the session variable: Yii:: app()->session['var']='value';                 (Recommended learning: yii framework)

Use: echo Yii::app( )->session['var']; Remove: unset(Yii::app()->session['var']);

How to use it more complicatedly Configure your session configuration items can be set in the components of protected/config/main.php:

'session'=>array(
   'autoStart'=>false(/true),
   'sessionName'=>'Site Access',
   'cookieMode'=>'only',
   'savePath'='/path/to/new/directory',
),

Keep the session in the database settings:

'session' => array (
    'class' => 'system.web.CDbHttpSession',
    'connectionID' => 'db',
    'sessionTableName' => 'actual_table_name',
)
