Ok. Been playing with all this to try to get it too work. Normally with a
function I could do the following:

$foo = "apples";

function myfunction () {
extract($GLOBALS);
$var = $foo;
print $var;
}

myfunction();

Outputs apples. Which is fine and tells me that extract($GLOBALS) puts all
variables I have defined available in the function. If I try to use this

extract($GLOBALS);

Inside my class definition I get the following error.

Parse error: parse error, expecting `T_OLD_FUNCTION' or `T_FUNCTION' or
`T_VAR' or `'}'' in /path/shoppingcart.inc.php on line 14

So I guess for some reason I can't use extract GLOBALS in a class.

When I try to use a defined constant when setting up my class variables then
it doesn't seem to stick. I would have thought the below should work.

var $password = SQL_PASSWORD;

But nothing seems to be assigned to $password.

If I try

var $password = $GLOBALS['password'];
or
var $password =& $GLOBALS['password'];

I get Parse error.

So it seems like the $GLOBAL keyword is what is causing the problem when
called inside a class. Does that make sense? It can't be that I am using
reserved keywords can it?
