[mapguide-users] Get selected layers from server side

Is it possible to get a list of the map's selected layers from the server
I know I can get this by making an MgSelection and passing the selection XML
from the client to the server program, like:
$selection = new MgSelection($map,$_REQUEST['selectionXML']);
However, I don't want to pass a big selection XML string to the server
program, as I am passing by GET and the selection XML could be greater than
the browser handles.
If I make the selection object without including the selection XML, like
$selection = new MgSelection($map);
$selectedLayers = $selection->GetLayers();
$numberLayers = $selectedLayers->GetCount();
PHP tells me that $selectedLayers is not an object.
