render('index'); } public function actionContact() { return $this->render('contact'); } }
all(); return $this->render('index', ['posts' => $posts]); } }In this example, we have created a new controller named `PostController` with an action named `actionIndex()`. This action retrieves all the records from the `post` table using the Yii ORM system and renders the `index` view with the retrieved data. Package/Library used: Yii ActiveRecord library In summary, Yii framework provides a rich set of tools and libraries to rapidly develop web applications in PHP. It provides solutions for common challenges such as authentication, caching, and database interactions. Yii follows the MVC pattern, which makes it easy to maintain code and separate concerns. The examples above show how to create controllers and actions, as well as how to retrieve data from the database using Yii ORM. The package/library used in the examples are Yii core library and Yii ActiveRecord library.
