That's containment, not inheritence, must have misread the email. Oops :)
The "easiest" way to do this would be something like:
class contrived {
private $parent;
private $otherparent;
public function __call($func, $params) {
if(is_callable(array($this->parent, $func))
call_user_func_array(array($this->parent, $func), $params)
elseif(is_callable(array($this->otherParent, $func))
call_user_func_array(array($this->otherparent, $func), $params)
}
}
This is the most "elegant" way to accomplish the same thing, but it makes
some assumptions, like you're willing to chain if-elseif's together (or
store all contained instances in an array) and that you don't ever have
overlapping method names (ie contrived.foo and parent.foo both exist).
Also, it's really, really obnoxiously slow. __call() is hardly fast and
call_user_func_array is no different.
