## What it is
amphp/amp is the core library of the AMPHP ecosystem, providing futures, coroutines, and cancellation primitives for non-blocking, event-driven concurrency in PHP. It builds on PHP 8.1 fibers and the Revolt event loop, letting developers write asynchronous code that reads like synchronous code.

## Use cases
- run multiple HTTP requests concurrently in PHP
- make non-blocking database queries in PHP
- write async PHP without callbacks or promise chains
- build WebSocket servers or chat bots in PHP
- parallelize I/O-bound tasks in a PHP CLI script
- cancel long-running async operations in PHP

## When to choose
- you have I/O-bound PHP workloads that benefit from concurrency
- you want fiber-based async code that looks synchronous
- you're building on the AMPHP or Revolt ecosystem of packages
- you need futures and structured cancellation primitives

## When to avoid
- your workload is CPU-bound rather than I/O-bound
- you're stuck on PHP versions older than 8.1
- your app is simple and blocking I/O causes no performance issues
- you need true parallelism across CPU cores (consider amphp/parallel or threads)

## Facets
- artifact type: library
- maturity: stable
- function: concurrency, http-client, websocket, middleware
- domain: web-development, backend, developer-tools, networking
- platform: php, cli, cross-platform
- tags: async, fibers, coroutines, futures, event-loop, non-blocking-io, revolt, cancellation, web-server
