This article illustrates the session and cookie operations of the Yii Framework Learning Note. Share it for your reference, as follows:

session operation

<?php
  namespace app\controllers;
  use yii\web\Controller;
  class HelloController extends Controller{
  　　  　　  public function actionIndex(){
     　　  // Put session As an object 
     　　  $session = \yii:$app->session;
     　　 if($session->isActive){
       　　  echo "session isactive";
     　　 }else{
       　　  $session->open();
     　　 }
     　　 $session->set("user"," Zhang 3");
     　　 $session->get("user");
     　　 $session->remove("user");
