我正在使用Stripe创建新的客户和订阅。返回客户和订阅对象时，它们类似于：

我是oop的菜鸟，但是我设法设置了一些变量以插入到mySQL表中，例如
$customerID = $customer->id;
但是我将如何获得订阅昵称值（从底部起约15行）。我尝试了各种迭代，例如：
$nickname = $subscription->plan->nickname;
但似乎没有任何作用。
有什么想法吗？
谢谢。

根据Patrick的评论进行编辑：
var_dump($subscription->plan->nickname);
输出：
string(7) "Monthly
，然后执行以下操作：
$output .= "Subscription Plan ID = $subscription->id<br />";
$output .= "Subscription Plan Nickname = $subscription->plan->nickname<br />";
echo $output;
输出：
Subscription Plan ID = sub_EhN9GgJfiFYmsV Subscription Plan
Nickname = Stripe\Plan JSON: { "id": "00030", "object": "plan", "active": true, "aggregate_usage": null, "amount": 999, "billing_scheme": "per_unit", "created": 1552107233, "currency": "usd", "interval": "month", "interval_count": 1, "livemode": false, "metadata": [], "nickname": "Monthly", "product": "prod_EfHkC7lwkSS1l3", "tiers": null, "tiers_mode": null, "transform_usage": null, "trial_period_days": 15, "usage_type": "licensed" }->nickname
答案 0 :(得分：0)
由于帕特里克（Patrick），我得以提出以下似乎可行的方法：
$nickname = print_r($subscription->plan->nickname, true);
$output .= "Subscription Plan Nickname = $nickname<br />";
echo $output;
结果：
Subscription Plan Nickname = Monthly
答案 1 :(得分：-1)
由于尝试访问嵌套数组，因此需要先将所需的值分配给变量，然后将其注入字符串中，或者需要将对象访问位用大括号括起来。
因此您可以执行以下操作：
$planNickname = $subscription->plan->nickname;
$output .= "Subscription Plan ID = $subscription->id<br />";
$output .= "Subscription Plan Nickname = $planNickname<br />";
echo $output;
或者您可以这样做：
$output .= "Subscription Plan ID = $subscription->id<br />";
$output .= "Subscription Plan Nickname = {$subscription->plan->nickname}<br />";
echo $output;
