包	system.web
继承	class CHttpSession » CApplicationComponent » CComponent

源码	framework/web/CHttpSession.php

CHttpSession provides session-level data management and the related configurations.

To start the session, call open(); To complete and send out session data, call close(); To destroy the session, call destroy().

If autoStart is set true, the session will be started automatically when the application component is initialized by the application.

CHttpSession can be used like an array to set and get session data. For example,

  $session=new CHttpSession;
  $session->open();
  $value1=$session['name1'];  // get session variable 'name1'
  $value2=$session['name2'];  // get session variable 'name2'
  foreach($session as $name=>$value) // traverse all session variables
  $session['name3']=$value3;  // set session variable 'name3'

The following configurations are available for session:

See the corresponding setter and getter documentation for more information. Note, these properties must be set before the session is started.

CHttpSession can be extended to support customized session storage. Override openSession, closeSession, readSession, writeSession, destroySession and gcSession and set useCustomStorage to true. Then, the session data will be stored and retrieved using the above methods.

CHttpSession is a Web application component that can be accessed via CWebApplication::getSession().
