seems to me that you're trying to have an object's member behave as if it
had global scope. you never say "$foo = new bar()". instead you say
"$this->foo = new foo()" where $this is an instance of Overall. you can't
instantiate a Foo as a member of an Overall instance, and then expect to
talk to that Foo without going thru the instance itself (which Jonathan
suggested).
so, either use $overall->foo to talk to the Foo instance, or you could do
this in Overall::load():
function load($class)
{
global $$class;
$$class = new $class();
$this->$class =& $$class;
}
which i think will create the Foo instance in global scope, and give the
Overall instance a member that is a reference to that same object.
