FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package websocket
ez-php/websocket
PHP 8.5 Fiber-based WebSocket server for the ez-php ecosystem.
Implements RFC 6455 from the ground up — no third-party WebSocket library needed. Each connection runs in its own Fiber, allowing hundreds of concurrent clients on a single PHP process without threads or async extensions.
Intentionally separate from ez-php/broadcast (SSE/event-bus); this module
provides bidirectional, low-latency real-time communication.
Installation
No framework integration is needed — the server runs as a standalone long-lived process.
Quick start
Start the server:
Connect from a browser:
Core classes
Server
- Opens a TCP server socket via
stream_socket_server() - Spawns one
Fiberper accepted connection - Non-blocking
stream_select()event loop resumes Fibers when sockets are readable - Handles PING→PONG and CLOSE frames automatically
ConnectionInterface / Connection
Frame
Represents one RFC 6455 frame. Available in HandlerInterface::onMessage():
ChannelManager
Named pub/sub channels over connected clients:
broadcast() silently prunes disconnected connections.
Architecture notes
- No message fragmentation reassembly: continuation frames are silently ignored. Real-world clients send single-frame messages for chat/notifications; large binary transfers should be chunked at the application level.
- No TLS (WSS): terminate TLS at a reverse proxy (nginx, Caddy) and use plain
ws://internally. - No authentication: verify cookies or tokens in
onOpen()and call$conn->close()on failure.
