| Thanks for your reply but I don't understand what you are asking me to
| do. Could you provide a code sample? I want "$item" to contain a
| reference ot the created object (as opposed a new copy) but I would
| then like to call a method from the object being referenced.

$items_arr = array();
$items_arr[0] = new CUserItem(1);
$itemTestA = &$items_arr[0];
$itemTestB = $items_arr[0];
$test = array(
'RAW DATA' => $items_arr ,
'BY REF' => $itemTestA ,
'BY VAL' => $itemTestB
);
print_r($test);

see what the differences are. does that help?
