simple object assocition

[Radim B]

Hi,

I need to share 1 object e.g. "UserPermission" to 2 others e.g.
"Document", "File" objects.
How can I make it without pointers? Many thanks for any help.

What do you mean with pointers? One way to go would be to extend the
UserPermission object with other objects.

I nearly always use a mediator:

class mediator{

function &obj_instance(){

static $instance;

if (!isset($instance)){
$instance = new obj();
}

return $instance;
}
}
You can access this in any (class) function with

$obj =& mediator::obj_instance();
In this version all $obj would use the same object, but you can
control that from within the mediator.
