如何从php中的复杂对象中获取值

Question

我正在使用 Google Calendar API，试图从响应对象中获取 ID。

这是对象。

Google_Service_Calendar_CalendarList Object
(
[collection_key:protected] => items
[internal_gapi_mappings:protected] => Array
    (
    )

[etag] => "1454629096373000"
[itemsType:protected] => Google_Service_Calendar_CalendarListEntry
[itemsDataType:protected] => array
[kind] => calendar#calendarList
[nextPageToken] => 
[nextSyncToken] => CIj2xtSj38oCEj1nY2FsL....
[modelData:protected] => Array
    (
        [items] => Array
            (
                [0] => Array
                    (
                        [kind] => calendar#calendarListEntry
                        [etag] => "145461934381000"
                        [id] => tbcv49j3eg@group.calendar.google.com
                        [summary] => Appointments
                        [timeZone] => America/Chicago
                        [colorId] => 24
                        [backgroundColor] => #a47ae2
                        [foregroundColor] => #000000
                        [selected] => 1
                        [accessRole] => reader
                        [defaultReminders] => Array
                            (
                            )

                    )

                [1] => Array
                    (
                        [kind] => calendar#calendarListEntry
                        [etag] => "14546290978873000"
                        [id] => o6lkfgdovcv2r8@group.calendar.google.com
                        [summary] => Test Calendar
                        [timeZone] => America/Chicago
                        [colorId] => 14
                        [backgroundColor] => #9fe1e7
                        [foregroundColor] => #000000
                        [selected] => 1
                        [accessRole] => reader
                        [defaultReminders] => Array
                            (
                            )

                    )

            )

    )

所以我这样做是为了将它们放入一个数组中。

foreach ($calendarList['items'] as $key => $value) {
     $ids[] = $calendarList['items'][$key]['id'];
}

但我想以更面向对象的风格引用它们，例如

$calendarList->items->

我可以这样做吗？

Answer 1

$calendarListNew=new stdClass();
$calendarListNew->items=new stdClass();

$i=1;
foreach ($calendarList['items'] as $key => $value) {
     $calendarListNew->items->$i = $calendarList['items'][$key]['id'];
     $i++;
}

因此您可以获取如下值：

$calendarListNew->items->{'1'}

Answer 2

$value会有各项，你可以用下面的

foreach ($calendarList['items'] as $key => $value) {
    $value = (object) $value;
    $ids[] = $value->id;
}
