## Description

PHP-Websockets is a network programming library that provides a persistent server implementation for handling bidirectional real-time communication. It functions as a framework for managing asynchronous data exchange between web clients and server-side application logic, enabling the development of responsive systems that react to incoming messages.

The library facilitates the hosting of WebSocket servers by managing persistent connections and pushing live updates to users. It handles the technical requirements of the protocol, including the validation of upgrade requests through handshake negotiation and the encapsulation of application data into binary frames for transmission.

The system operates using an event-driven execution model that polls for network activity to trigger callbacks without blocking the main process. It manages raw socket streams and buffers incoming data fragments in memory to ensure complete messages are assembled before being passed to the application layer.
