How to download and install the yii2.0 framework
Before installing the Yii2.0 framework, you must first install the PHP web environment on the Windows system. This is a prerequisite for PHP development. When installing the PHP web environment on Windows, you can choose some integrated environments, which are very convenient to install with one click, such as phpstudy.
Confirm whether the composer tool is installed, win R, cmd to enter the command line, enter composer to check whether it is installed. If it is not installed, please install the composer tool first.
In the PHP web environment, create the installation directory of the yii2.0 framework. I use the phpstudy integrated environment, create the yii2 directory in the phpstudy\WWW\ directory, and later install the basic and advanced versions of yii2 in this directory.
win R, enter cmd to enter the Windows command line. Enter the created yii2 directory.
To install the basic version of the yii2.0 framework, execute the command:
composer create-project --prefer-dist yiisoft/yii2-app -basic basic
#Test whether the basic version is installed successfully. Enter: http://localhost/yii2/basic/web/index.php in the address bar of the browser. The premise is that the php web service is running.

When preparing for an interview with Yii framework, you need to know the following key knowledge points: 1. MVC architecture: Understand the collaborative work of models, views and controllers. 2. ActiveRecord: Master the use of ORM tools and simplify database operations. 3. Widgets and Helpers: Familiar with built-in components and helper functions, and quickly build the user interface. Mastering these core concepts and best practices will help you stand out in the interview.

Yii framework adopts an MVC architecture and enhances its flexibility and scalability through components, modules, etc. 1) The MVC mode divides the application logic into model, view and controller. 2) Yii's MVC implementation uses action refinement request processing. 3) Yii supports modular development and improves code organization and management. 4) Use cache and database query optimization to improve performance.

Yii is a high-performance PHP framework designed for fast development and efficient code generation. Its core features include: MVC architecture: Yii adopts MVC architecture to help developers separate application logic and make the code easier to maintain and expand. Componentization and code generation: Through componentization and code generation, Yii reduces the repetitive work of developers and improves development efficiency. Performance Optimization: Yii uses latency loading and caching technologies to ensure efficient operation under high loads and provides powerful ORM capabilities to simplify database operations.

Yii2 is a powerful PHP framework that has been widely praised by developers. With its high performance, scalability and user-friendly interface, it becomes ideal for building large, complex web applications. However, like any framework, Yii2 has some advantages and disadvantages to consider.

Developing a RESTful API in the Yii framework can be achieved through the following steps: Defining a controller: Use yii\rest\ActiveController to define a resource controller, such as UserController. Configure authentication: Ensure the security of the API by adding HTTPBearer authentication mechanism. Implement paging and sorting: Use yii\data\ActiveDataProvider to handle complex business logic. Error handling: Configure yii\web\ErrorHandler to customize error responses, such as handling when authentication fails. Performance optimization: Use Yii's caching mechanism to optimize frequently accessed resources and improve API performance.

With the continuous development of PHP framework technology, Yi2 and TP5 have attracted much attention as the two mainstream frameworks. They are all known for their outstanding performance, rich functionality and robustness, but they have some differences and advantages and disadvantages. Understanding these differences is crucial for developers to choose frameworks.

In 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())
