+
+# Now we access the first four items in list (three are C++ objects that
+# EmployeeList's constructor adds, the last is our CEO). The virtual
+# methods of all these instances are treated the same. For items 0, 1, and
+# 2, both all methods resolve in C++. For item 3, our CEO, getTitle calls
+# getPosition which resolves in PHP. The call to getPosition is
+# slightly different, however, from the e.getPosition() call above, since
+# now the object reference has been "laundered" by passing through
+# EmployeeList as an Employee*. Previously, PHP resolved the call
+# immediately in CEO, but now PHP thinks the object is an instance of
+# class Employee (actually EmployeePtr). So the call passes through the
+# Employee proxy class and on to the C wrappers and C++ director,
+# eventually ending up back at the CEO implementation of getPosition().
+# The call to getTitle() for item 3 runs the C++ Employee::getTitle()
+# method, which in turn calls getPosition(). This virtual method call
+# passes down through the C++ director class to the PHP implementation
+# in CEO. All this routing takes place transparently.

+# Time to delete the EmployeeList, which will delete all the Employee*
+# items it contains. The last item is our CEO, which gets destroyed as its
+# reference count goes to zero. The PHP destructor runs, and is still
+# able to call the getName() method since the underlying C++ object still
+# exists. After this destructor runs the remaining C++ destructors run as
+# usual to destroy the object.
