yii2打开session
useyii\web\Session;
 
$session = Yii::$app->session;
// check if a session is already openif($session->isActive) ...
// open a session$session->open();
// close a session$session->close();
// destroys all data registered to a session.$session->destroy();

设置session
$session = Yii::$app->session;
$session->set('user_id', '1234');
//OR$session['user_id'] = '1234';
//OR$_SESSION['user_id'] = '1234';

读取session
$session = Yii::$app->session;
$user_id = $session->get('user_id');
//OR$user_id = $session['user_id'];
//OR$user_id = isset($_SESSION['user_id']) ? $_SESSION['user_id'] : null;
销毁session$session = Yii::$app->session;
$session->remove('user_id');
//ORunset($session['user_id']);
//ORunset($_SESSION['user_id']);

数组session的读取与设置

$session = Yii::$app->session;
$session['user'] = ['id' => 1,
    'username' => 'yiiuser',
];
echo$session['user']['id'];
echo$session['user']['username'];
 
$session['user.id'] = 1;
$session['user.username'] = 'yiiuser';
