What does 'final class' and 'final function' (final method) mean in PHP?

PHP: What does 'final class' and 'final function' (final method) mean in PHP?

If a class is defined as final class then no other class can extend it. I.e. the following would result in an error:

  1.         final class DontExtendMe {}
  2.         class ThisCausesAnError extends DontExtendMe {}

A final method (final function ...) means that any subclasses of it's class cannot be overridden.
