Hmm, on my system:

    <?php
    
       header("Content-type: text/plain");
       print_r($MarkupTable[$id]['dep']);
       print_r((array)$MarkupTable[$id]['dep']);
       print_r((array)($MarkupTable[$id]['dep']));
    
       var_dump($MarkupTable[$id]['dep']);
       var_dump((array)$MarkupTable[$id]['dep']);
       var_dump((array)($MarkupTable[$id]['dep']));
    ?>

produces

    Array
    (
    )
    Array
    (
    )
    NULL
    array(0) {
    }
    array(0) {
    }

which is pretty much what I would expect.  It certainly
doesn't show any elements in the (array) versions...
