$user = Auth::getUser(); echo "Your email address is: " . $user->email;
if (Auth::check()) { $user = Auth::getUser(); echo "Welcome " . $user->name; } else { echo "Please log in to access this page."; }In this example, the Auth check function is used to determine if the user is currently logged in. If they are, the getUser function is used to display a personalized welcome message. If not, the user is prompted to log in. It is difficult to determine a specific package library based on these examples alone, as they could be using any number of PHP authentication libraries. However, some popular options include Laravel's built-in authentication system, the PHP Authentication Library, or the Simple Authentication Library.
