Develop multi-functional live broadcast system using PHP
With the popularization of mobile Internet and the development of voice and video technology, live broadcast has become an increasingly popular Internet application. Live streaming can be used in various fields such as entertainment, education, and commerce, and has great potential in conveying information, promoting products, and communicating and interacting. Therefore, it is very necessary to develop an efficient and stable live broadcast system.
This article will introduce how to use PHP to develop a multi-functional live broadcast system, including basic functions, technical architecture and implementation methods. By studying this article, you can have an in-depth understanding of the application of PHP technology in the development of live broadcast systems, and at the same time, it can provide reference and help for your own development of live broadcast systems.
1. Basic functions
- Video collection and processing: The live broadcast system first needs to collect the user's video and process the video. Video collection can be carried out through cameras, mobile phones and other devices, while video processing includes video format conversion, video encoding, bit rate control and other processes to ensure that the video can achieve the best effect during transmission. With the support of PHP technology, open source libraries such as FFmpeg can be used to capture and process videos.
- Video transmission and storage: The live broadcast system needs to transmit the processed video to the server for storage and play it to the audience. PHP technology can help us realize the transmission and storage of videos. By using HTTP protocol or RTMP protocol for transmission, and using relational databases such as MySQL for storage, efficient and stable video transmission and storage can be achieved.
- Video playback and viewing: The live broadcast system needs to provide the audience with video playback and viewing functions. PHP technology can help us realize the functions of video playback and viewing, including video format conversion, video encryption technology, video playback control, etc.
2. Technical Architecture
- Front-end technical architecture: The front-end technical architecture needs to realize the video playback and viewing functions. Since live streaming requires real-time playback and interaction, technologies such as websocket need to be used to achieve real-time communication between the front and back ends. The front-end technical architecture also needs to take into account different clients such as mobile and PC to achieve a cross-platform live broadcast system.
- Back-end technology architecture: The back-end technology architecture needs to realize a series of functions such as video collection, processing, transmission and storage. PHP technology can help us realize these functions, and we also need to use server software such as nginx to achieve video transmission and load balancing.
3. Implementation method
- VOD mode implementation: VOD (Video On Demand) mode refers to the use of protocols such as HLS to achieve on-demand playback, which can provide a better user experience . Using the VOD mode can realize the user's on-demand playback function, and maintain the index information and playback address of the video while storing the video.
- P2P mode implementation: P2P (Peer to Peer) mode refers to using the viewer as a transit node for video transmission and using a relatively advanced P2P algorithm to realize video transmission. The P2P mode can significantly reduce the bandwidth burden on the server, provide a more stable video playback effect, and also prevent the server from being attacked by sudden traffic.
4. Summary
Through the introduction of this article, we can see the importance of PHP technology in the development of live broadcast systems. By using PHP technology, the live broadcast system can be multi-functional, efficient and stable, and improve user experience and development efficiency. At the same time, this article also introduces the technical architecture and implementation methods of the live broadcast system, and proposes implementation ideas for VOD and P2P modes, hoping to be helpful to PHP live broadcast system developers.

Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
