使用此代码

从中构建数组

if($response->ResponseMessages->FindFolderResponseMessage->RootFolder->TotalItemsInView > 0){

    $folders                                                            = $response->ResponseMessages->FindFolderResponseMessage->RootFolder->Folders->Folder;

    foreach($folders as $folder){
        $calname                                                    = $folder->DisplayName;
        $id                                                         = $folder->FolderId->Id;
        $ChangeKey                                                  = $folder->FolderId->ChangeKey;
        $parentid                                                   = $folder->ParentFolderId->Id;
        $parentchangekey                                            = $folder->ParentFolderId->ChangeKey;

        $foldersExchange[$id]['name']                               = $calname;
        $foldersExchange[$id]['folderid']                           = $id;
        $foldersExchange[$id]['changekey']                          = $ChangeKey;
        $foldersExchange[$id]['parentid']                           = $parentid;
        $foldersExchange[$id]['parentchangekey']                    = $parentchangekey;
    }
}

$ foldersExchange的结果

结果我正在寻找

            [parentchangekey] => AQAAAA==
                )
    )

我不知道怎么做，因为我构建的数组的关键元素不同，所以我没有共同的标识符。

您对如何实现此结果有任何提示吗？
