#Is Yii framework a lightweight framework?
The Yii framework is not a lightweight framework. The Yii framework is already considered a heavyweight among the PHP frameworks. The framework is a component-based high-performance PHP framework for developing large-scale Web applications, and adopts strict Written in OOP, it also provides almost all the functions needed for web application development.
Yii Features
Yii has almost all the features for today's Web 2.0 application development. Below is a short list of these features.
Model-View-Controller (MVC) design pattern: Yii adopts this mature technology in WEB programming to better separate the logic layer and presentation layer.
Database Access Object (DAO) and Active Record: Yii allows developers to model data objects in a database, thereby reducing their effort in writing long and repetitive SQL statements.
Integration with jQuery: As one of the most popular JavaScript frameworks, jQuery can write efficient and flexible JavaScript interfaces.
Form Input and Validation: YII makes collecting form input very easy and secure. Yii has a set of validators to ensure the validity of data. It also has helper methods and components to display errors when validation fails.
Web 2.0 Widgets: Powered by jQuery, YII comes with a set of Web 2.0 widgets such as autocomplete input fields, TreeView and more.
Authentication and Authorization: Yii has built-in authentication support. It also supports authorization through layered role-based access control (RBAC).
Theme: It can instantly change the view of a Yii application.
Web Services: Yii supports automatically generating complex WSDL service specifications and managing Web service request processing.
Internationalization (I18N) and Localization (L10N) : Yii supports message conversion, date and time formats, number formats and interface localization.
Hierarchical caching scheme: Yii supports data caching, page caching, fragment caching and dynamic content. A cached storage medium that can be easily changed without touching the application code.
Error handling and logging: Error handling is well presented, and log information can be classified, filtered and assigned to different locations.
Security: Yii comes with many security measures to help secure web applications to prevent network attacks. These measures include cross-site scripting (XSS) prevention, cross-site request forgery (CSRF) prevention, cookie tampering prevention, etc.
XHTML Compliant: Yii components and command line tools generate code that is XHTML compliant.
Automatic code generation: Yii provides tools that can automatically generate code according to your needs, such as generating a program skeleton, CRUD application, etc.
Completely object-oriented: Yii framework adheres to a strict object-oriented programming paradigm. It does not define any global functions or variables. Moreover, the class hierarchy it defines allows for maximum reusability and customization.
Friendly using third-party code: Yii is carefully designed to make third-party code work very well. For example, you can use PEAR or Zend Framework code in your Yii application.
Detailed documentation: Every single method or attribute is recorded very clearly. A comprehensive tutorial and some beginner tutorials are also provided.
Extension Library: Yii provides an extension library composed of user-provided components, which makes the list of above features never-ending.

How to display error prompts in yii2Apr 18, 2025 pm 11:09 PMIn Yii2, there are two main ways to display error prompts. One is to use Yii::$app->errorHandler->exception() to automatically catch and display errors when an exception occurs. The other is to use $this->addError(), which displays an error when model validation fails and can be accessed in the view through $model->getErrors(). In the view, you can use if ($errors = $model->getErrors())
