Hi ..
Basically, its trying to create an associate multi-dimensional array .....
for example ..
[PHP]
// Inside the loop ..Lets suppose that the First value is ..

$rs_main_menu['id'] = "A1";

$array_Itemid[$rs_main_menu['id']] = array();

// In the above statement this value is used to define the key of the array...like..
$array_Itemid['A1'] = array();

$array_Itemid[$rs_main_menu['id']][] = $rs_main_menu['id'];
// Then in the next statement it assigns the value to the array ...like

$array_Itemid['A1'][0] = "A1";

// So for each row it will ...create the array elements[/PHP]

Hope I explained it clearly .....if any doubt ...feel free to ask
good luck ! :)
