Question

我有一种转换为std对象的json字符串。由AWS SNS返回，一些转换为数组，一些转换为Std对象属性。我试图从这些解码属性“[bouncedRecipients]”，它有时是一个数组，有时它是一个std对象属性。

无法随身携带，因为我尝试的是代码，只有在它的JSON对象属性但不作为数组工作时才有效。

$mail=json_decode($data->bounce->bouncedRecipients);

以下是返回数据类型的示例。其他变量类型[bouncedRecipients]成为std对象属性。

假设您已经解码了JSON数据，那么你可以做这样的事情：

foreach ($data->bounce->bouncedRecipients as $bouncedRecipient) {
    // $bouncedRecipient is an object so use it as such, ie.
    echo $bouncedRecipient->emailAddress;
}

如果您需要检查类型，您还可以执行以下操作：

if (is_object($data->bounce->bouncedRecipients)) {
    $data->bounce->bouncedRecipients = [$data->bounce->bouncedRecipients];
} elseif (!is_array($data->bounce->bouncedRecipients)) {
    die("What is this data you have given me?");
}

然后继续前面的foreach或类似的循环。

Json转换为Std对象并访问Std对象的不同数据类型（即数组或属性）？
