Q on "inhert" class code

I have a parent Class that does this in one of it's methods... $session = &Auth::_importGlobalVariable("session"); $session[$this->_sessionName]['registered'] = true; I would like to "hook" into this in on eof my methods in a child class I thought I could do this... [538] $session = Auth::_importGlobalVariable("session"); [539] $session[Auth::_sessionName]['registered'] = true; But I get this error: Parse error: parse error, unexpected ']', expecting '(' in mypath\AuthUser.php on line 539 OK, I guessed wrong (again). This is how PEAR::Auth deals with inserting its class vars into a session and I want to piggyback on that. No need to roll my own, I think. Can someone show me the errors of my ways? Thanks Walter
