通过兄弟键从 AWS SDK (describeInstances) 选择多维数组成员
Selecting multidimensional array member from AWS SDK (describeInstances) by sibling key
我在 php 上使用 AWS SDK 来获取远程桌面客户端的实例信息。我已经包含了一个我正在检索的数组成员的示例。我已经通过此数组中提供的标签之一进行过滤，以仅接收组 "ABC" 的项目。过滤后，我想为数组的每个成员检索另一个称为 "clientId" 的标记的值。因为索引不一致，所以我不能通过 $results['Instances'][0]['Tags'][0]['Value] 简单地 select 项目。有时它是不同的数字（如 $results['Instances'][0]['Tags'][1]['Value]）。我想根据其兄弟 (Key => clientId) select 它，但我找不到这样做的方法。
感谢您提供的任何帮助。
