Preface

The Yii\web\controller class is a more commonly used class, and the Yii2 controller inherits this class. About the Yii\web\controller class, in fact, YII2 document also has, why should I write this article? There may be a lot of people wondering .... I think so, Yii2 the document is there is no mistake, but that is for the public, and there is no instance, let people look at or is more laborious, if someone can read every class, and then release specific examples, is it more comfortable to look at it? Do you understand more quickly?
