Authorize.net PHP致命错误：调用数组

Question

上的成员函数getSubscriptionDetailType（）我创建Authorize.net定期计费报告，我得到订阅数组列表。

$subscriptions[] = $response->getSubscriptionDetails(); 

当我尝试回声内部数组值象下面这样，我得到这个错误 “PHP致命错误：在阵列调用一个成员函数getSubscriptionDetailType（）”

echo $subscriptions[0]->getSubscriptionDetailType()->id; 

我想的var_dump看看这是怎么回事这个数组里面..我得到这个结果

array(1) { 
 
    [0]=> 
 
    array(1) { 
 
    [0]=> 
 
    object(net\authorize\api\contract\v1\SubscriptionDetailType)#200 (16) { 
 
     ["id":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     int(4362259) 
 
     ["name":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     string(29) "MetroCare Dental Subscription" 
 
     ["status":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     string(7) "expired" 
 
     ["createTimeStampUTC":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     object(DateTime)#195 (3) { 
 
     ["date"]=> 
 
     string(26) "2017-02-06 17:02:50.287000" 
 
     ["timezone_type"]=> 
 
     int(3) 
 
     ["timezone"]=> 
 
     string(3) "UTC" 
 
     } 
 
     ["firstName":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     string(5) "javed" 
 
     ["lastName":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     string(5) "Malik" 
 
     ["totalOccurrences":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     int(1) 
 
     ["pastOccurrences":"net\authorize\api\contract\v1\SubscriptionDetailType":private]=> 
 
     int(1) 
 
    } 
 
    } 
 
}

var dump显示订阅详细信息 - 对象位于另一个数组内的数组中。两个数组包含一个元素（偏移0），因此这将是：

$response[0][0]->getSubscriptionDetails();
