Introduction to the implementation steps of the mutual follow function developed by PHP

With the popularity of social networks, the mutual follow function has become one of the necessary functions for many websites and APPs. Whether it is Weibo, WeChat, Facebook, or Instagram, users can get more information and interactions by following other users. In PHP development, it is not complicated to implement the mutual follow function. This article will introduce the steps to implement the mutual attention function developed in PHP.

1. Database design
   Before starting development, you first need to design the database. The mutual follow function requires at least two tables: user table and follow table. The user table records the user's basic information, such as user ID, user name, avatar, etc.; the follow table records the following relationship between users, such as follower ID and followed person ID. You can add some additional fields to the follow table, such as follow time, to facilitate more operations on follow relationships in the future.
2. User registration and login
   In order to realize the mutual follow function, users first need to register and log in. You can use common usernames and passwords to log in, or you can use third-party logins, such as Weibo, QQ, etc. When a user registers, relevant information needs to be saved in the user table.
3. User Follow
   To implement the user follow function, you can add a follow button next to each user information on the user's personal homepage or user list page. When the user clicks the follow button, the follower ID and followed person ID are sent to the server through an Ajax request. After receiving the request, the server saves the attention relationship to the attention table. At the same time, the number of followers and followed numbers of relevant users also need to be updated so that they can be displayed on the user's personal homepage or user list page.
4. User Unfollow
   Users can also unfollow other users. To unfollow, you can add an unfollow button next to each followed user information on the user's personal homepage or user list page. When the user clicks the unfollow button, the follower ID and followee ID are also sent to the server through an Ajax request. After receiving the request, the server deletes the corresponding follow relationship in the follow table. At the same time, the number of followers and followed numbers of relevant users also need to be updated.
5. Watch list and fan list
   Users can view their own watch list and fan list. The following list displays other users that the user has followed, and the fan list displays other users that have followed the user. By querying the attention table, the relevant attention relationships can be obtained. Displaying the follow list and fan list on the user's personal homepage makes it easier for users to view and manage their followers and fans.
6. User dynamic reminder
   After the user logs in, if other users follow him, the user can be reminded through system messages or push notifications. When users receive the follow reminder, they can check the information of the users who follow them and decide whether to follow them back.
7. Friend Recommendation
   In order to increase the interaction between users, you can recommend some potentially interested users to the user based on the user's attention relationship. The algorithm analyzes the user's watch list and fan list to find other users with similar interests to the user and make recommendations to the user.

Summary
Through the above steps, we can implement a simple mutual follow function. Of course, actual development may also involve other functions, such as user search, user profile modification, etc. Through reasonable database design and PHP development technology, we can easily implement an application with mutual attention function. I hope this article can provide some help to PHP developers in implementing the mutual follow function.
