if (!Auth::isLogged()) { header("Location: login.php"); exit(); }
if (Auth::isLogged()) { echo "Welcome back, " . Auth::getUser()["name"] . "!"; }In this example, the `Auth::isLogged()` function is used to display user-specific content. If the user is logged in, their name is displayed on the screen. The `Auth::isLogged()` function is typically part of a larger authentication library or package. Examples of such libraries/packages include Laravel's authentication library, Symfony's security component, and the PHP-Auth library.
