PHP Session Mechanism Explained

The PHP Session mechanism is a technology used to track user session status in web applications. It allows for persistence of user data across different pages, allowing users to maintain their login status and other relevant information while browsing the same website.

Specifically, the PHP Session mechanism works by storing user session data on the server and assigning a unique session ID to each user. This allows for identifying and retrieving user information across pages, enabling data sharing and persistence.

In general, the purpose of the PHP Session mechanism is to assist developers in managing user session states, allowing users to smoothly navigate the website and maintain a personalized user experience.
