Its been a while since I worked with PHP but to my recolection it works like
all the other interfaces. When you execute a statement it returns an object
that contains the result set. Accessing that result set remains valid until
destroyed even if other results are returned in the interim. If you keep
assinging the result object to the same variable then the assignment
implicitly destroys the previous result object.
