为什么这个输出是空白的？
我知道我一定做错了一些简单的事情。当我这样做时：
echo '<pre>';
print_r($event->when);
echo '</pre>';
我得到这个：
Array
(
[0] => Zend_Gdata_Extension_When Object
(
[_rootElement:protected] => when
[_reminders:protected] =>
[_startTime:protected] => 2011-06-16T10:00:00.000-05:00
[_valueString:protected] =>
[_endTime:protected] => 2011-06-17T11:00:00.000-05:00
[_rootNamespace:protected] => gd
[_rootNamespaceURI:protected] =>
[_extensionElements:protected] => Array
(

[_extensionAttributes:protected] => Array
(
)
[_text:protected] =>
[_namespaces:protected] => Array

[atom] => Array

)
)
[rss] => Array
(

)
)
)
)
)
然后我试图通过这样做来获取 startTime：
$StartTime = $event->when->startTime;
但我什么也没得到。
然而，当我这样做时：
pr($event->published);
我得到这个：
Zend_Gdata_App_Extension_Published Object
(
[_rootElement:protected] => published
[_rootNamespace:protected] => atom
[_rootNamespaceURI:protected] =>
[_extensionElements:protected] => Array
(
)
[_extensionAttributes:protected] => Array
(
)
[_text:protected] => 2011-06-15T03:32:14.000Z
[_namespaces:protected] => Array

(
[0] => http://purl.org/atom/app#
)
[2] => Array
(
[0] => http://www.w3.org/2007/app
)
)
)
)
我可以这样做：
$dateAdded = $event->published->text;
echo $dateAdded;
并且我看到一个输出......
I know I must be doing something simple wrong. When I do this:
echo '<pre>';
print_r($event->when);
echo '</pre>';
I get this:
Array

)
)
I'm then trying to get startTime by doing this:
$StartTime = $event->when->startTime;
But I'm not getting anything.
And yet, when I do this:
pr($event->published);
I get this:
Zend_Gdata_App_Extension_Published Object
(
[_rootElement:protected] => published
[_rootNamespace:protected] => atom
[_rootNamespaceURI:protected] =>
[_extensionElements:protected] => Array
(
)
[_extensionAttributes:protected] => Array
(
)
[_text:protected] => 2011-06-15T03:32:14.000Z
[_namespaces:protected] => Array
(
[atom] => Array
(
[1] => Array

[app] => Array

(
[0] => http://purl.org/atom/app#
)
[2] => Array
(
[0] => http://www.w3.org/2007/app
)
)
)
)
and I can do this:
$dateAdded = $event->published->text;
echo $dateAdded;
and I see an output...

根据 官方 Zend_Gdata_Extension_When 文档，有一个名为 < code>getStartTime() 这会给你时间。
如果您执行
$event->when[0]->getStartTime()或$event->when[0]->startTime，您将获取开始时间。According to to the official Zend_Gdata_Extension_When documentation, there's a method called
getStartTime()which will give you the time.If you do
$event->when[0]->getStartTime()or$event->when[0]->startTime, you'll get the start time.startTime被标记为受保护。你不能像你一样从外部引用它。该对象中必须有一个 getter 函数“getStartTime()”，该函数允许您公开引用它。编辑：它还返回一个对象数组 - 而不是单个对象，因此您需要像这样引用它：
$event[0]->getterFunction()或使用 a 循环遍历数组foreach访问循环中的各个对象startTimeis marked protected. You can't reference it from outside like you did. There must be a getter function 'getStartTime()' function in that object that would allow you to reference it publicly.EDIT: Also it is returning an object array - not an single object, so you would need to reference the it like:
$event[0]->getterFunction()or loop through the array with aforeachaccessing the individual objects in the loop
