There's a few ways to do it... probably simplest way for you would be
to do something like this inside your class..
$var =& $GLOBALS['var']; // this will only create a reference to the
global variable $var inside your object. If you want a copy take out the
& ($var = )
hope that helps..
btw if you have any variable that you need to "change" and its too much
hasle... sometimes a good workaround is this exact "trick" ...
$oldVar =& $NEW_VAR; doesn't take up any new resources as you're only
creating a "pointer" not a duplicate ..
