Scope woe

Hello again guys, I was wondering the best way to tackle the following problem: I've got a class, containing a property which is another object. So from outside I should be able to do $firstobject->propertycontainingobject->methodinsidethatobject(); The $firstobject variable is in the global namespace (having been made with $firstobject = new FirstObject;), and I'm having a problem that I'm sure many people have when accessing it inside another class, so: class otherObject { static function messwithotherthings () { $firstobject->propertycontainingobject->methodinsidethatobject(); } } But $firstobject is blank, which makes sense because in there it is pointing to the local variable within the method. To solve this, I could add 'global $firstobject' inside every method, but this is very redundant and boring. I've tried a couple of things like adding: private $firstobject = $GLOBALS['firstobject']; But apparently that's bad syntax. I was just wondering the best way to get around this? Thanks a lot for your help, -- Luke Slater :O)
