I'm probably trying to understand something that simply isn't viable in OO, but I'd prefer to learn from my mistakes than still have it niggling at the back of my mind. It basically comes down to this: How can I access this | v $Core->Error->Something ^ From this | Consider the Car class: <?php class Brakes { ... } class Lights { ... } class Car { var $brakes, $lights; function Car() { $this->brakes = new Brakes; $this->lights = new Lights; } } ?> I can't use 'extends' in this instance, because I don't want to mix up the braking and the electrical system. However I do want to access the electrical system if I hit the brake - to turn on the brake light. If I *did* in fact use 'extends', I would use parent::lights->something() to access the objects within Car. Is there some way of creating an equivalent for sub-objects? Perhaps with references? NOTE: An option I've tried would be to have Lights extend Car, however that gives me problems with the constructor. When I initialise the extension, I'm also initialising a new instance of Car. If I don't call the constructor, I can't access the extended objects. If I do, I'm in a loop. I'm not making sense, am I? adam
