This article describes the use of Yii framework Session and cookies. Share it for your reference, as follows:
Yii Session Use
public function actionIndex(){
$session = \YII::$app->session;
//Judge whether the session is on if(!$session->isActive) {
//Not enabled, need to be enabled $session->open();
}
//Set session $session->set('user_name','zhangsan');
//Get session $user_name = $session->get('user_name');
echo $user_name;
//Delete session $session->remove('user_name');
//Array session //Set session $session['userName'] = 'lisi';
//Get session $user_name = $session['userName'];
echo $user_name;
//Delete session unset($session['userName']);
}
Use of Yii cookies
public function actionIndex(){
//Set cookies (note that the response component is used here) $cookies = \YII::$app->response->cookies;
$cookie_data = array('name'=>'user','value'=>'zhangsan');
$cookies->add(new Cookie($cookie_data));
//Get cookies (note that the request component is used here) $cookie = \YII::$app->request->cookies;
echo $cookie->getValue('user','default_value');//The second parameter is the default value when it does not exist //Delete cookies (note that the response component is used here) $cookies->remove('user');
}
