SWoole Introduction

SWoole is a high-performance, asynchronous, event-driven PHP extension for building high-performance Concurrent, low-latency web applications.

Main features

High performance and scalability:

• Utilize multi-process and multi-threading to fully Utilize server hardware resources.
• Supports multi-protocol concurrent processing, such as HTTP, WebSocket and UDP.

Asynchronous and non-blocking:

• Based on the Reactor model, using the event loop mechanism to process requests.
• Will not block the PHP process, thereby improving concurrent processing capabilities.

Low latency:

• Use underlying I/O multiplexing technology such as epoll to achieve fast response.
• Optimize cache and data structure to reduce processing overhead.

Other features:

• Built-in HTTP and WebSocket servers.
• Provides rich API and event callbacks.
• Supports coroutines to simplify asynchronous programming.
• Compatible with PHP 7.0 and higher.

Application scenarios

SWoole is widely used in high-traffic and high-concurrency scenarios, such as:

• Web services
• WebSocket Service
• Live Chat
• Game Development
