Answer 1

Implement your user class with IdentityInterface yii\web\IdentityInterface In your configuration file

'user' => 
[
    'identityClass' => 'app\models\User', 
]

Then You may use this code to get user id in your view files as

$user = \Yii::$app->user->identity;
if (!empty($user){
   echo "<h2>User: {$user->id}</h2>";
}
