Article Introduction：Whether or not the PHP framework is necessary depends on project requirements and development habits. For medium and large projects, using frameworks can improve code quality and save development time because frameworks provide standardized structures (such as MVC mode), built-in common functions (such as database operations, routing, authentication), enhanced security (such as anti-SQL injection), and integrated auxiliary tools (such as cache, queues). 1. The advantages of the framework include: standardizing code structure, improving maintenance, accelerating development speed, enhancing security, and integrating common functions. 2. The situation where the framework is not used is: small or one-time project, high-performance requirements scenarios, and basic skills practice during the learning stage. 3. Use the framework to pay attention to: learning costs are high, flexibility is limited, and performance overhead is present. It is recommended to choose appropriate based on the project size and personal ability.

Article Introduction：Unit testing is an important means to ensure code quality in C# projects and must be implemented. 1. Select the appropriate testing framework: such as xUnit, NUnit or MSTest, and decide based on team habits or project needs; 2. Reasonably organize the test code: establish a test structure according to the main project structure image, and each test method only tests one behavior, keep it concise and clear; 3. Use the Mock framework to isolate dependencies: such as Moq or NSubstitute, simulate external dependencies to ensure test independence; 4. Automatically run tests and integrate CI/CD: configure automatic testing in GitHubActions and other processes to prevent error merging, and can be set to run automatically during local development.

Article Introduction：Gii is a powerful code generation tool in the Yii framework, which accelerates the development process by generating boilerplate code based on database structure or input parameters. Specifically, Gii can generate ActiveRecord models, create controllers containing CRUD operations, build corresponding views, and help build components such as modules and forms. To enable Gii, add 'gii' to the 'bootstrap' array in the configuration file config/web.php, and configure its class and access restricted IP in the 'modules' section. Gii helps keep code consistency and conforms to Yii best practices and is suitable for quickly building data-intensive applications such as CMS or management panels. Although the generated code is a skeleton,

Article Introduction：Choosing a CSS framework or native CSS depends on project requirements and team proficiency. Using frameworks such as Bootstrap or Tailwind can speed up development with prefabricated components, especially for prototypes or time-critical projects, but requires learning naming specifications and tool patterns; while native CSS does not require additional syntax, suitable for small projects or situations where full control is required. Frameworks may cause code redundancy and need to be manually optimized to avoid performance problems, while native CSS is more flexible but is slow to develop and prone to inconsistent. In teamwork, frameworks help unify styles and simplify handovers, but over-customization can cause confusion, while native CSS is easier to debug due to its simple structure. Therefore, both have their own advantages and disadvantages, and should be based on development efficiency, customization, performance and
