Session Management in Core PHP Diagrammed

 HTTP requests are inherently stateless, meaning each request from a client to a server is independent, with no inherent connection to previous requests. This stateless nature poses challenges when maintaining continuity and user-specific data across multiple interactions with a web application. PHP addresses this issue through session management, as depicted in the diagram. By using sessions, PHP allows for the storage of user-specific data on the server, while a session ID stored in the client’s browser cookie ties individual requests together. This approach enables PHP to maintain state across multiple requests, allowing for a consistent user experience despite the stateless nature of HTTP. The diagram illustrates how PHP handles session creation, continuity, and expiration, ensuring that user data persists across different interactions with the application.
