$order = Mage::getModel('sales/order');
$order->loadByIncrementId(100000001); // 100000001为订单编号
// 获取订单状态
$status = $order->getStatus();

Magento订单 有两个状态变量：state和status，这让人困惑，只有测试下了，于是下了个单，然后在Magneto后台处理订单，得出下面的Magento订单状态值。
1. 新订单
state : new
status : pending
2. 配送后
state : processing
status : processing
3. 收款后
state : processing
status : processing
4. 订单完成
state : complete
status : complete
5. 订单取消
state : canceled
status : canceled
6. 订单关闭
state : closed
status : closed
7. 订单挂起
state : holded
status : holded
8.支付（Paypal, Amazon Pay）过程中引入的订单状态
state : pending_payment
status :payment_review
Magento订单状态 是定义在Magento代码文件app\code\core\Mage\Sales\Model\Order.php中定义了订单的状态常量：
/**
* Order model
*
* Supported events:
* sales_order_load_after
* sales_order_save_before
* sales_order_save_after
* sales_order_delete_before
* sales_order_delete_after
*
* @author Magento Core Team <core@magentocommerce.com>
*/
class Mage_Sales_Model_Order extends Mage_Sales_Model_Abstract
{
/**
* Order states
*/
const STATE_NEW = 'new';
const STATE_PENDING_PAYMENT = 'pending_payment';
const STATE_PROCESSING = 'processing';
const STATE_COMPLETE = 'complete';
const STATE_CLOSED = 'closed';
const STATE_CANCELED = 'canceled';
const STATE_HOLDED = 'holded';
const STATE_PAYMENT_REVIEW = 'payment_review'; // added magento 1.4
/**
* Order flags
*/
const ACTION_FLAG_CANCEL = 'cancel';
const ACTION_FLAG_HOLD = 'hold';
const ACTION_FLAG_UNHOLD = 'unhold';
const ACTION_FLAG_EDIT = 'edit';
const ACTION_FLAG_CREDITMEMO= 'creditmemo';
const ACTION_FLAG_INVOICE = 'invoice';
const ACTION_FLAG_REORDER = 'reorder';
const ACTION_FLAG_SHIP = 'ship';
const ACTION_FLAG_COMMENT = 'comment';
// ...
}

其中，pending_payment, payment_review 是支付（Paypal, Amazon Pay）过程中引入的订单状态。
