我是 Laravel 的新手，我正在迈出第一步。所以我做了这个查询：
public function getPaymentHistory($user_id)
{
return $this->where('created_by', '=', $user_id)->orderBy('created_at', 'desc')->get();
}
这是结果：
Pyro\Module\Streams\Entry\EntryCollection Object
(
[model:protected] => Pyro\Module\Payment\Model\PaymentModel Object
(
[table:protected] => payment
[timestamps] => 1
[columns:protected] => Array
(
[0] => *
)

(
[0] => id
)
[createdByUserColumns:protected] => Array

[2] => email

问题，我如何获取或访问以下值：
[attributes:protected] => Array
(
[id] => 2
[created_at] => 2014-06-17 16:03:15
[updated_at] =>
[created_by] => 18
[ordering_count] => 2
[transactionID] => 93P86838PY273320N
[orderTime] => 2014-06-20 02:02:38
[toReload] => 54.680000305176
[amt] => 56
[feeAmt] => 1.9199999570847
[currencyCode] => USD
[paymentStatus] => Completed
[pendingReason] => None
)
这就是我调用模型的方式：
$payment = new PaymentModel();
$payment_history = $payment->getPaymentHistory($user->id);
