Yes, I solved the above problem myself. Solution like below:

$combinations_obj = (object) array("requested_quantity" => $product_combination->product_combination[0]->requested_quantity);
$combination_data->combinations[] = $combinations_obj;
$product_challan_infos->product_combination_list[] = $combination_data;
