## What it is
amphp/http-server is a non-blocking, concurrent HTTP/1.1 and HTTP/2 application server library for PHP built on the Revolt event loop and Amp fibers. It supports TLS, middleware, routing, static file serving, sessions, and WebSockets via companion packages.

## Use cases
- build a high-concurrency async HTTP API server in PHP
- serve real-time apps with WebSockets in PHP
- run a non-blocking HTTP/2 server with TLS
- handle many concurrent I/O-bound requests without blocking
- build a chat bot or real-time backend on an event loop
- serve static files alongside dynamic routes in PHP

## When to choose
- your PHP app is I/O-bound and needs high concurrency
- you want fiber-based async code instead of promise chains
- you need WebSockets or long-lived connections in PHP
- you want an application server without nginx/php-fpm request-per-process overhead

## When to avoid
- your app relies heavily on blocking PHP built-in I/O functions
- you need a simple CRUD site better served by a traditional framework
- your team is unfamiliar with async/concurrency concepts
- you need CGI-style hosting on shared PHP environments

## Facets
- artifact type: library
- maturity: stable
- function: http-server, websocket, routing, middleware, static-site-generator
- domain: web-development, backend, apis
- platform: php, cli, cross-platform
- tags: async, event-driven, non-blocking, revolt, fibers, http2, tls, composer, amphp, real-time
