Reactphp
ReactPHP is an asynchronous runtime and event-driven I/O framework for PHP. It provides an environment for executing concurrent tasks through a central event loop implementation and reactor pattern, allowing applications to handle multiple operations without pausing the main execution thread.
The project includes a specialized asynchronous socket library for TCP, UDP, and TLS communication, alongside a non-blocking HTTP server and client for streaming web requests and responses.
Its capability surface covers asynchronous control flow via promises and fibers, non-blocking network connectivity including DNS resolution, and system integration for managing child process execution and I/O piping. It also provides event-driven stream interfaces and asynchronous data caching to maintain responsiveness during heavy I/O operations.
Features
- Event-Driven I/O - Implements a complete event-driven I/O framework using a reactor pattern for high-concurrency PHP applications.
- Asynchronous Event Loops - Provides a central reactor-based event loop that monitors file descriptors and triggers I/O callbacks.
- Asynchronous Socket Libraries - Provides a specialized toolset for non-blocking TCP, UDP, and TLS network connections.
- Connection Managers - Provides utilities to manage multiple concurrent TCP and TLS socket connections asynchronously.
- Event-Driven Networking - Enables the creation of high-performance TCP, UDP, and TLS servers that manage many simultaneous connections.
- Non-Blocking Socket I/O - Wraps native network sockets in a non-blocking layer to prevent execution stalls during data transfer.
- Asynchronous Control Flows - Manages the completion and failure of non-blocking tasks using promises to ensure continuous execution.
- Asynchronous Flow Coordination - Coordinates concurrent operations using promises and fibers to simplify complex asynchronous control flows.
- Asynchronous PHP Development - Provides the runtime and primitives necessary for building non-blocking, concurrent applications in PHP.
- Asynchronous Event Loops - Coordinates the execution of asynchronous tasks and event notifications via a central reactor pattern.
