How can you check if a session has been destroyed in PHP?

When a session is destroyed in PHP, the session data is cleared and the session ID is invalidated. To check if a session has been destroyed, you can use the session_status() function in PHP. If the session status is equal to PHP_SESSION_NONE, then the session has been destroyed. 

if(session_status() === PHP_SESSION_NONE){
    echo "Session has been destroyed.";
} else {
    echo "Session is active.";
}
