php editor Youzi will take you to explore the mysteries of the Yii framework and reveal its architecture and best practices. As a high-performance PHP framework, the Yii framework is famous for its simplicity, efficiency and flexibility, and is widely used in web development. By having an in-depth understanding of the design ideas, core architecture, and best practices of the Yii framework, developers can better utilize the features of the framework, improve development efficiency and code quality, and implement better web applications.

• represents business logic and data interaction.
• Perform database operations through Active Record mode.
• Use validation rules and relationships to ensure data integrity.

View (V)

• Rendering the applicationFrontendinterface.
• Use Twig template engine to render the page.
• Provide reusable components and layouts.

• Application component: Provides common services such as user authentication and caching.
• LogLogging component: records application events and errors.
• Internationalization and localization components: supports multi-language applications.

Best Practices

ORM use

• Use Active Record mode for database operations.
• Define validation rules and relationships to ensure data integrity.

Code Organization

• Use namespaces to organize code.
• Place controllers, models, and other classes in the appropriate directories.
• Use PSR-4 autoloading standard.

Safety

• Use CSRF protection to prevent cross-site request forgery.
• Use data filtering and validation to prevent injection attacks.
• Use strong password hashing algorithms to protect user data.

performance

• Use caching to reduce database queries.
• Use paging and sorting to optimize database queries.
• Use the Gii code generator to quickly create code scaffolding.

test

• Use unit tests to verify the logic of controllers and models.
• Use functional tests to test end-to-end scenarios.
• Use testing frameworks such as Codeception.

Other Best Practices

• Follow the naming convention of the Yii framework.
• Use Composer to manage dependencies.
• Update the framework and components regularly.
• Read the Yii documentation for the latest information.
