In PHP, a final class is a class that cannot be inherited or extended by other classes. It is declared using the final keyword. Final classes are used when you want to prevent further extension or inheritance of a class. A final method, on the other hand, is a method within a class that cannot be overridden by any subclass. It is also declared using the final keyword. Final methods are used when you want to enforce that a specific method should not be overridden in any subclass.
