How To Use Session Destroy in PHP?

Before we learn about destroying a session in PHP, we must have some knowledge about the session.

Basically, a session is defined as a method that is used to store web page visitor preferences on a web server in the form of variables. These methods can be reused across different pages.

When a session is opened at the beginning of each web page, the information is retrieved from the web server and similarly, when the web page is closed by the user, the session ends.

The requirement to destroy sessions arises when the user clicks on the logout button. This is because we do not need any information from the user at this point since the user is logged out.
