$user = new User(); $id = $user->getId(); echo "User ID: ".$id;
function getUserById($userId){ $user = new User(); $user->loadById($userId); return $user->getId(); } $id = getUserById(5); echo "User ID: ".$id;In this example, we created a function getUserById that accepts a user ID as a parameter. We then create a new User object, load the user data by ID and return the user ID. Finally, we call the getUserById function by passing the user ID as a parameter and print the user ID on the screen. Package/Library: It is not possible to determine the package/library information just by knowing the function name getId. It is likely part of a custom class created within the application.
