If you want to destroy only a session single item, you use the unset() function.
In order to create a session, you must first call the PHP session_start function and then store your values in the $_SESSION array variable.
Sessions use a cookie PHPSESSID to store session ID. Unlike a cookie, the information is not stored on the users computer.
Session ID can be either stored on user’s computer in a cookie or can be passed along with URLs.
PHP cookies Sessions are passed in browser cookies, which are little extra bits of information that get sent to and from a web browser. Examples might be simplified to improve reading and basic understanding. A cookie is a small file with the maximum size of 4KB that the web server stores on the client computer.
It’s still a cookie, but it’s called PHPSESSID and is typically stored in the /tmp/ directory on the web server itself.

A session is a group of information on the server that is associated with the cookie information. If the client browser does not support cookies, the unique php session id is displayed in the URL; Sessions have the capacity to store relatively large data compared to cookies. $_COOKIE array can contain depends on the memory size set in php.ini.Let’s assume you have saved your PHP files in phptus folder.
Whenever a session is created, a cookie containing the unique session id is stored on the user’s computer and returned with every request to the server. The main difference between cookies and sessions is that information stored in a cookie is stored on the visitor's browser, and information stored in a session is not—it is stored at the web server.

If you're using PHP you can check the session. With PHP, you can both create and retrieve cookie values. These are known as third party cookies. Let’s suppose we want to know the number of times that a page has been loaded, we can use a session to do that. In PHP sessions can be identified using session ID. Unset only frees the individual session variables. This difference determines what each is best suited for.
