In most cases json_encode should be called once only. Keep adding all you want to convert to JSON in a php array, then call json_encode

$json = array('items' => array());
foreach ($items as $item) {
    $json['items'][] = array(
       'itemName' => $item->name
    );
};

echo json_encode($json);

You could also call json_encode for all your $items array without doing a loop

json_encode($items)
