OOP-related question

Hey, I have the following script: class overall { function overall(){ $this->loaded['overall'] =1; function load($class){ $$class = new $class; $this->loaded[$class] = 1; $$class->setup(); // Run constructor if(!is_object($$class)){ return false; } return true; } } then I have a few classes, which hold a setup() function as thei 'constructor'. Then, I do this: $overall = new overall; $overall->load('debug'); this should load the debug class. I want it to load to $debug->, but it won't even load to $overall->debug It's not really a *need* to have this, it's just something that will help me in keeping control over all classes. I don't want to use new class, because this way it would be easier to 'instruct' the 'constructor' of those new classes to change the values of the vars to a specific one, without calling for something weird... anyway, it doesn't work, and it doesn't spit out an error either. Any ideas? - Tularis
