In this paper, an example is given to explain how Yii framework operates cookie and session. Share it for your reference, as follows:

cookie operation

Setting cookie

// Get response->cookies Component 
$cookies = \Yii::$app->response->cookies;
// Settings cookie Array 
// Add cookie Data 
$cookies->add(new Cookie($array_cookies));

Delete cookie


Read cookie

$cookies = \Yii::$app->request->cookies;
echo $cookies->getValue("user");

Careful people may find that reading cookie is slightly different from the previous components, which are response->cookies While reading uses request->cookies Why is this? You can refer to the principle of saving cookie with response and reading cookie with request in the framework of Yii in the previous article

session operation

In the Yii framework for session operation, we are through a called session component things, first we need to get session component.

$session = \Yii::$app->session;

After obtaining the session component, to operate on session, we first need to determine whether session is enabled

if ($session->isActive){
  echo "session Has been opened ";

After session has been turned on, we can set up and use session data. First, set up session data

$session->set("user"," Zhang 3");

Reading session data is also simple

$user = $session->get("user");

Similarly, there is deleting session data


In addition, we can operate session as an array

// Settings session
$session['user'] = ' Zhang 3';
// Read session
$user = $session['user'];
// Delete session
