How to use PHP session in 2021
PHP session is a variable that stores all the values of user input.
Session: A session typically starts when a browser requests a web page from a server. The server assigns the browser an id and saves this id in the session's "sid" cookie. The server then responds to the request by sending back a response containing an encrypted version of the "sid" cookie.
In PHP, this information is stored in $_SESSION[‘sid’];
For you to fetch your current session ID from PHP, you need to type in $_SESSION['sid'];
