This project is intentionally small and incomplete. It is designed for learning and demo servers, not production use. Purpose ------- [](#purpose) - Show how HTTP/2 frames can be encoded/decoded in a simple way. - Provide a tiny server-side flow for one request stream and one response. - Keep implementation readable without full RFC complexity. Supported Frame Types (Minimal Subset) -------------------------------------- [](#supported-frame-types-minimal-subset) - `SETTINGS` (basic ACK handling) - `PING` (basic ACK handling) - `HEADERS` (request stream detection, no header decoding) - `DATA` (request end detection, response trigger) The frame codec itself can encode/decode generic frame envelopes (9-byte header + payload). Unsupported Features -------------------- [](#unsupported-features) - Full HTTP/2 compliance - Request header decoding (HPACK decode) - CONTINUATION handling - Dynamic table (HPACK) - Huffman encoding (HPACK) - Flow control enforcement - Stream prioritization / multiplexing - Multi-stream request handling (demo is single-stream) - Production-grade validation and error handling Server Architecture ------------------- [](#server-architecture) - `Frame`: immutable frame value object - `FrameCodec`: binary frame encoder/decoder - `HpackEncoder`: minimal response header block encoder - `ConnectionState`: mutable per-connection state - `FrameHandler`: tiny server-side state machine - `ResponseBuilder`: creates `HEADERS` + `DATA` response frames ReactPHP Example ---------------- [](#reactphp-example) See `examples/react-http2-server.php`. What it does: 1. Accepts a TCP connection (`h2c` prior knowledge). 2. Reads and validates the HTTP/2 client preface. 3. Sends an empty server `SETTINGS` frame. 4. Buffers incoming bytes and repeatedly calls `FrameCodec::tryDecode()`. 5. Passes each decoded frame to `FrameHandler`. 6. Encodes returned frames and writes them back. 7. Sends a single plain text response body: `hello from http/2 server\n`. 8. Closes the connection after the response. Run example: ``` php examples/react-http2-server.php 8080 ``` Test with curl: ``` curl -v --http2-prior-knowledge http://127.0.0.1:8080/ ``` Client Architecture ------------------- [](#client-architecture) The client example is also intentionally minimal and educational. - `ClientConnectionState`: mutable state for one connection - `RequestBuilder`: builds one GET request HEADERS frame on stream 1 - `ClientFrameHandler`: handles SETTINGS/ACK flow and minimal response events - `ClientConnection`: ReactPHP connection wrapper around buffer/decode/write loop ### Client Limitations [](#client-limitations) - client only - HTTPS + ALPN(h2) only - single GET request only - one request stream only - no response header decoding - no HPACK decoder - no CONTINUATION support - no multiplexing / retries / flow-control enforcement - small responses / demo only - not production-ready ### Client Example Flow [](#client-example-flow) See `examples/http2-client.php`. 1. Parse `[--insecure] `. 2. Connect via TLS with ALPN `h2,http/1.1`. 3. Send client preface + empty SETTINGS. 4. Decode frames with `FrameCodec::tryDecode()`. 5. On server SETTINGS, send SETTINGS ACK and one GET HEADERS frame. 6. Print DATA payload bytes to STDOUT. 7. Close on END\_STREAM or GOAWAY. ### Health Score 31 — LowBetter than 66% of packages Maintenance79 Regular maintenance activity Popularity0 Limited adoption so far Community6 Small or concentrated contributor base Maturity33 Early-stage or recently created project Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
