[PHP] Weird problem with objects

[Mark Cubitt]

hi,

I have a shopping cart I'm having probs with.

I have a cart class that starts like this:

<CODE>

require_once("class_database.php"); // Database Class
require_once("class_accessory.php"); // Accessory Class
require_once("class_order.php"); // Order Class

class cart
{

        var $database;
        var $accessory;
        var $order;

        function cart() {

                $this->$database = new database();
                $this->$accessory = new accessory();
                $this->$order = new order();

        } // end function cart

</CODE>

and has a line like this:

<CODE>

$price = $this->$accessory->get_accessoryPrice("$key");

</CODE>

there is a get_accessoryPrice function in the accessory class,

but it won't work unless I use this line instead:

<CODE>

$price = $this->$$this->$accessory->get_accessoryPrice("$key");

</CODE>

This makes no sense to me what so ever, so can anybody shed some light on it
for me.
I'm prob just making a silly mistake but any help would be very much
appreciated.

Thanks in advance

Regards

Mark Cubitt
