$category = Category::getInstanceByID(5); // Fetches the category object with ID 5 $name = $category->getName(); // Gets the name of the categoryIn this example, we use the getInstanceByID method to fetch the category object with ID 5. We then use the getName method to get the name of the category. It is difficult to determine the package library without more context. However, the Category class is likely part of a library or framework that provides functionality for managing data in categories.
