Development process of live broadcast system combined with PHP

With the rapid development of the Internet and the popularity of social media, live broadcast has become a very important part of today's online world. Various industries and fields can promote, market and communicate through live broadcast. This article will introduce the development process of the live broadcast system and the technologies involved based on the development process of the live broadcast system in PHP.

1. Project background

This project was developed to meet the needs of users for online live broadcasting. Through the live broadcast system, users can conduct real-time video broadcasts, and viewers can interact with the anchors. In addition, this system also includes some additional functions, such as gift rewards, chat rooms, etc.

2. Requirements Analysis

Before starting to develop the live broadcast system, we first need to understand the needs of users and conduct demand analysis. Through analysis, we have clarified the needs in the following aspects:

1. Real-time video broadcast: Users can perform real-time video broadcast, and viewers can watch it on the platform.
2. Audience interaction: Audiences can interact with the host while watching the video.
3. Gift Rewards: Viewers can send various virtual gifts to the host through the platform, and the host can view the gifts received.
4. Chat Room: Audiences can communicate and interact in the chat room.
5. User management: The system must have user management functions, including registration, login, password change, etc.

3. Technology Selection

After implementing the demand analysis, we need to select the technology. This system uses the following technologies:

1. WebRTC technology: WebRTC is a real-time communication technology that can perform real-time audio and video communication in the browser. It can achieve high-quality audio and video transmission. We use WebRTC technology to implement real-time video broadcast functionality.
2. PHP framework: We use Laravel as the back-end framework to implement the development of user management, chat rooms, gift rewards and other functions.
3. MySQL database: We use MySQL database to store user information, chat records, gift records and other data.
4. JavaScript: We use JavaScript to implement the front-end implementation of WebRTC technology.

4. System Development

1. User Management

User management is one of the core functions of the entire system. Users need to register, log in, change passwords and other operations. When a user registers, we need to verify the user's legitimacy to prevent malicious registration. After the user logs in, we need to verify the user's identity and save the user status to the session. If there is no user information in the session, the user will not be able to chat or live broadcast.

2. Chat Room

Chat room is an important place for users to communicate and interact. In order to realize the chat room function, we need to implement the following parts:

(1) Chat box: realize the function of users sending messages.

(2) User list: Displays the list of online users in the current chat room.

(3) Message list: Display the chat history in the chat room.

In addition, we also need to implement the broadcast message function of the chat room so that users can see messages sent by other users to achieve real-time communication.

3. Live video

In order to implement the live video function, we need to use WebRTC technology.

(1) Build a signaling server: WebRTC requires a signaling server to coordinate and control video communication.

(2) Establish p2p video connection: Establish p2p video connection through signaling server to realize real-time video broadcast.

4. Gift Rewards

Gift rewards are an important part of the live broadcast system. Viewers can send various virtual gifts to the host through the platform, and the user who sent the gift will be displayed in the chat room. In order to implement the gift reward function, we need to implement the following parts:

(1) Gift list: Display the list of supported virtual gifts.

(2) Gift Reward: After the user selects a gift, the system will display the gift animation and display the user who sent the gift in the chat room.

5. Summary

This article introduces the development process of the live broadcast system and the technologies involved by combining the development process of the live broadcast system with PHP. During the development process, we need to conduct demand analysis based on user needs and select appropriate technologies to implement different functions. In the process of implementing functions, we need to pay attention to data security and user experience.
