Workerman is an asynchronous event-driven PHP socket framework that enables building fast and scalable network applications with high concurrency handling.
The framework addresses the challenge of handling concurrent network connections in PHP by providing an event-driven architecture that processes multiple connections asynchronously. It supports HTTP, WebSocket, SSL, and custom protocols, allowing developers to build diverse network services. The tool includes coroutine support for writing asynchronous code in a more synchronous style, along with utilities like Barrier for task synchronization, Parallel for concurrent task execution, Channel for inter-coroutine communication, and Pool for managing resource reuse such as database connections.
Workerman suits projects requiring real-time bidirectional communication or high-concurrency server applications where traditional PHP request-response models fall short. It requires a POSIX-compatible operating system and the POSIX and PCNTL extensions, with Event, Swoole, or Swaw extensions recommended for optimal performance. Coroutine features specifically require Swoole, Swaw, or Fiber with revolt/event-loop support. The framework is particularly valuable for WebSocket servers, chat applications, real-time notifications, and TCP-based services that need to maintain persistent connections.
The project maintains active engagement with its community through a Gitter channel and comprehensive documentation. Development activity shows consistent refinement of core features, with particular attention to coroutine and resource management capabilities. The codebase demonstrates stability in supporting multiple event loop backends, allowing users to choose the extension that best fits their deployment environment.
