Detailed explanation of push notification technology in PHP development of mutual attention system

Abstract:
With the continuous development of social networks, mutual attention systems have become more and more The more popular it becomes. This article will focus on the push notification technology of mutual attention systems in PHP development, including the definition, implementation and usage scenarios of push notifications.

1. Introduction:
Mutual following system plays an important role in social networks. It is the basis for users to follow each other and can easily realize instant communication and interaction between users. Push notification technology can improve the user experience and real-time performance of the mutual attention system. This article will introduce in detail the push notification technology commonly used in mutual attention systems in PHP development.

2. Definition of push notification:
Push notification means that in the mutual attention system, when a user generates important updates or has new news, the system can automatically push the relevant information Push to other users who follow this user in real time. Push notifications can be implemented in a variety of ways, such as SMS, email, instant messaging, etc.

3. How to implement push notifications:

1. Long polling technology:
   Long polling means that after the client sends a request to the server, the server does not directly return the result. Instead, the request is suspended and returned to the client when relevant data is updated. In the mutual following system, when a user generates new updates or has new messages, the server can push them to other users who follow the user in real time through long polling.
2. WebSocket technology:
   WebSocket is a full-duplex communication protocol that enables two-way communication on a TCP connection. In the mutual attention system, WebSocket technology can be used to implement real-time push notification function. When there are new updates or messages, the server can directly push them to the users who follow the user without the need for the client to actively send requests.

4. Usage scenarios of push notifications:

1. New dynamic message notifications:
   In the mutual follow system, when a user posts new updates , the dynamics can be pushed to other users who follow the user in real time through push notifications, improving the real-time performance and user experience of the system.
2. New private message notification:
   When a user receives a new private message, the message can be pushed to the relevant user in real time through push notification, so that the user can reply to the private message in a timely manner and improve the user experience. communication efficiency between them.
3. Friend status update notification:
   When a user's friend status changes, if a user unfollows or adds a new follow, the corresponding update information can be pushed to the association in real time through push notifications Users, allowing users to keep up to date with their friends’ updates.

5. Advantages of push notification technology:

1. Real-time: push notifications can be pushed to associated users in real time when users generate new updates or have new messages, improving the system real-time and user experience.
2. Efficiency: Push notifications can directly push relevant information to associated users without requiring users to actively refresh the page or send requests, improving communication efficiency and interactive experience between users.
3. Save resources: Push notifications can be implemented through long polling or WebSocket, reducing unnecessary network requests and saving server and bandwidth resources.

6. Application examples of push notification technology:
Nowadays, the mutual follow system has become an indispensable part of social networks, and push notification technology is also widely used in the mutual follow system. application. Taking WeChat Moments as an example, when a user posts a new update, the system will push the update to the user's friends in real time through push notifications, so that friends can see the update and interact with it in a timely manner.

Conclusion:
Push notification technology is an indispensable part of the mutual attention system, which can improve the real-time performance and user experience of the system. This article introduces in detail the push notification technology commonly used in PHP development of mutual attention systems, including the definition, implementation and usage scenarios of push notifications. The application of push notification technology is also widely used in social networks, improving the efficiency of interaction and communication between users. I believe that with the continuous development of technology, push notification technology will have wider applications and development.
