Introduction to yii operation session examples, yiisession examples

This article briefly describes the method of using session in Yii framework. The specific steps are as follows:

1. Differences from standard php code:

In Yii framework, you don’t need to use session_start() like standard PHP code,
In the Yii framework, the autoStart attribute is set to true by default, so,
Although session_start() is not used, you can still use the $_SESSION global variable, but it is best to use Yii::app->session

encapsulated by the Yii framework

2. Use of session variables:

Set session:

Yii::app()->session['var']='value';

Use session:

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

Remove session:

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

How to configure your session for more complicated use
Configuration items can be set in components of protected/config/main.php:

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

Keep session in database settings:

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

In addition, for debugging, sometimes you need to know the session ID of the current user,
The value is at:

Yii::app()->session->sessionID

Finally, when the user logs out (logout), you need to eliminate traces, you can use:

Yii::app()->session->clear() 

Remove all session variables, then call

Yii::app()->session->destroy() 

Remove session data stored on the server side.
