我尝试使用两者来解析以下（$var）
$convert = json_encode($var);
$object = (object)json_decode($convert);
$array = json_decode($convert, TRUE);
但似乎无法通过 $array->messages->event 之类的方式访问值（通常看不到任何内容/null）。
我一直在交叉引用https://gist.githubusercontent.com/eurica/6034108/raw/10e7fbce580e515db0f0b74d49c812da4e5ce40b/PagerDutyWebhookToEmail.php上的一些示例代码。但是，它似乎已过时（v1 有效负载而不是 v2）。
我的目标是在不同级别提取不同的值来创建自定义电子邮件。文档表明“消息”下可能有多个“消息”，因此可能需要一个 foreach？
