maybe your Close() function should be different?:

private function Close() {
$this->obj->ActiveDocument->Close();
}

but I still think your problem is the creation of multiple COM objects...

the download on following page might give you a hint as to other methods
which are available:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbawd11/html/WordVBAWelcome_HV01135786.asp

and there is this:
http://netevil.org/talks/PHP-and-COM-2005.pdf

which might help (it's by Wez Furlong, one of the core php guys)

sorry I can't help more.
