将数组和stdObject的混合解码到数据库

Question

我正在尝试将一组json文件解码为mysql数据库，并将解码后的值返回给数据表进行演示。我有一个名为ec2_instances的表，并希望向该表发送一个值数组，这些值位于cfi配置，工作正常。但现在添加了一个名为aws account id的新列，它位于对象而不是数组上我已更新模型以包含新列，但我正在努力

    $ret = $matches[0];
    foreach ($ret as &$match)
    {
        $match = $match == strtoupper($match) ? strtolower($match) : lcfirst($match);
    }
    return implode('_', $ret);
