If the class doesn't have a property with the given name, a ReflectionException will be raised.

Accessing private properties is possible, but care must be taken if that private property was defined lower into the inheritance chain. For example, if class A extends class B, and class B defines a private property called 'foo', getProperty will throw a ReflectionException.

Instead, you can loop over getParentClass until it returns false to look for the private property, at which point you can access and/or modify its value as needed.
