How to pass data from controller to view in Yii
The most common way to pass data using the render() method is. In the controller, data is passed through associative arrays, and the key name becomes a variable in the view; 2. Use view->params to share data, such as page title or breadcrumbs in multiple views or layouts; 3. You can directly pass model or object instances, suitable for CRUD operations and integrate well with widgets such as ActiveForm; 4. In Yii3 or advanced mode, you can use view components to encapsulate data logic, but in most cases the render() method is sufficient; the output must always be escaped to prevent XSS, and data should be prepared at the controller or service layer rather than handling complex logic in the view.
