Note Submitter: bryan dot thale at motorola dot com ---- In reply to ryan dot m dot lange: The behavior of your ChildClass2 class is exactly what should be expected. The constructor of ChildClass2 is not setting ParentClass::foo because that member is private and not visible to ChildClass2. Instead, it is dynamically defining and setting a new public $child2->foo member. $child2->foo() outputs nothing because foo() is inherited from ParentClass and the private ParentClass::foo member is unset. ParentClass's constructor is not automatically invoked by PHP since ChildClass2 defines its own constructor. ChildClass2::__construct() would have to explicitly invoke parent::__construct() if you wanted to chain constructors. $child2->bar() outputs the value of $child2->foo since that is the member that is visible to $child2.
