In what scenarios would it be more appropriate to use sessions instead of passing variables directly between PHP files for tasks like login verification or form processing?

Using sessions would be more appropriate for tasks like login verification or form processing where you need to persist data across multiple pages or requests. Sessions provide a way to store variables that can be accessed throughout a user's browsing session, making it easier to pass data between different PHP files without having to pass variables directly through URLs or forms. 

// Start a session
session_start();

// Set a session variable for login verification
$_SESSION['logged_in'] = true;

// Retrieve the session variable in another PHP file
session_start();
if($_SESSION['logged_in']){
    // User is logged in
} else {
    // User is not logged in
}
