With the development and popularization of the Internet, people increasingly rely on the Internet to obtain information and communicate. The campus community website is a popular online social platform that provides a place for communication, sharing, and interaction on campus. This article will introduce the basic steps and necessary functions to use the Yii framework to create a campus community website.

1. Create a new Yii project
First, you need to create a new Yii project in the local environment. Using Composer can easily and quickly build a Yii project. Enter the following command on the command line:

composer create-project yiisoft/yii2-app-basic basic

This command will download the Yii2 application basic template (yii2-app-basic) Go to the current directory and install the required packages based on the dependencies in the composer.json file. After running, execute the following command in the basic directory to create the database:

php yii migrate

2. Create the backend management system
In the Yii framework, use the Gii tool to quickly generate the backend Code to manage the system. Gii is the code generator of the Yii framework, which can help users quickly create code for models, controllers, and views. Using Gii requires some settings in the application's configuration file. After setting up, you can visit "http://yourdomain.com/index.php?r=gii" to enter the Gii tool page.

Select the "Model Generator" option on the Gii tool page to generate the database table model code for the campus community website. Then select the "CRUD Generator" option to generate code for operations pages such as additions, deletions, modifications, and queries.

3. Implement the login and registration function
The campus community website needs to implement the login and registration function. You can use the authentication and authorization components that come with the Yii framework to achieve this function. Implement the login and registration logic code in the controller, and implement the corresponding form page in the view. In the authentication and authorization components, use session to save user login information for reuse in future actions.

4. Realize the community function
The community function is the core of the campus community website, including multiple functional modules such as forums, blogs, photo albums, and activities. These functions can be developed using the MVC pattern of the Yii framework.

1. Forum function: The forum module includes functions such as posts and replies. Use the GridView component that comes with the Yii framework in the view to display the post list, and at the same time, you can implement the post and reply forms in the view.

2. Blog function: The blog module includes functions such as editing and displaying personal blogs. Use the ActiveForm component that comes with the Yii framework in the view to implement the blog editing and submission functions.

3. Photo album function: The photo album module includes functions such as uploading and browsing photos. Use the file upload component (FileInput) that comes with the Yii framework in the view to implement the photo upload function, and use the GridView component to display the photo list.

4. Activity function: The activity module includes functions such as publishing and registration. Use the form component that comes with the Yii framework in the view to implement event publishing and registration functions.

5. Implement the message push function
The campus community website needs to implement the message push function so that users can get message reminders as soon as possible. This functionality can be achieved using the message queue component of the Yii framework. Whenever there is a new message, the message queue component will automatically push the message to the user in the background and save the message to the database.

6. Testing and Deployment
After completing the development of the campus community website, it needs to be tested and deployed. During the test, each functional module needs to be tested to ensure that it can be used normally. During deployment, you need to upload the website to the server and configure the relevant environment and parameters.

The above are the basic steps and necessary functions to create a campus community website using the Yii framework. Using the Yii framework can achieve rapid development, improve development efficiency and code quality, and also provide strong scalability and maintainability for the website.
