Session

The Session of Yii 2 is relatively simple, just operate it directly through \Yii::$app->session

1) Add a session             (Recommended learning: yii tutorial)

<?php
$session = \Yii::$app->session;
$session->set(&#39;smister_name&#39; , &#39;myname&#39;);
$session->set(&#39;smister_array&#39; ,[1,2,3]);
?>

2) Read a session

<?php
$session = \Yii::$app->session;
//读取一个Session
$session->get(&#39;smister_name);
?>

3) Delete Session

<?php
$session = \Yii::$app->session;
//删除一个session
$session->remove(‘smister_name’);
//删除所有session
$session->removeAll();
?>
