What is the best way to clear or reset the $_SESSION superglobal in PHP?

To clear or reset the $_SESSION superglobal in PHP, you can simply call the session_unset() function followed by session_destroy(). This will remove all variables from the session and destroy the session data. It's important to note that this will not unset the session cookie, so the session ID will still exist until the browser is closed or the cookie is manually deleted.

session_start();
session_unset();
session_destroy();
