在PHP 5.2中是否有与DateTime :: diff()等效的函数?
我的本地服务器是PHP 5.3并使用DateTime :: diff().然后我发现我的实时网站使用PHP 5.2并给出错误.
Fatal error: Call to undefined method DateTime::diff() in /var/www/some/other/dir/web/daikon/modules/projects/views/admin/log/admin_log_list.php on line 40

在C#中,给定一组任意的DayOfWeek终点(如DayOfWeek.Friday和DayOfWeek.Sunday),如何测试任意日期是否在这两天之间,包括?
例:
// result == true; Oct 23, 2010 is a Saturday
var result = InBetweenDaysInclusive(new DateTime(2010, 10, 23),
DayOfWeek.Friday,
DayOfWeek.Sunday);
// result == true; Oct 22, 2010 is a Friday
result = InBetweenDaysInclusive(new DateTime(2010, 10, 22),
DayOfWeek.Friday,
DayOfWeek.Sunday);
// result == true; Oct 24, 2010 is a Sunday
result = InBetweenDaysInclusive(new DateTime(2010, 10, 24),
DayOfWeek.Friday,
DayOfWeek.Sunday);
// result == false; Oct 25, 2010 is a Monday
result = InBetweenDaysInclusive(new DateTime(2010, 10, 25),
DayOfWeek.Friday,
DayOfWeek.Sunday);

我记得读过以下功能导致在Python中开发有趣的框架/库: - (我从http://www.python.org/workshops/2002-02/papers/09/index.htm阅读了这篇文章)
Java是静态编译的,它也有一个垃圾收集器.我想知道它的班级模型是否可以简单,但是,请记住上面提到的几点,我有以下疑问: -
这个问题我快要疯了!
我在虚拟机上为TFS创建了一个新服务器.
我创建了一个新的Build Definition,当从我的本地机器上签入解决方案时,TFS将使用默认的构建过程模板构建我的解决方案.
在TFS机器和我的本地机器上,我安装了MS Office 2010和.Net framework 4.0.
在我的项目中,我引用了Microsoft.Office.Interop等...
这一切都在我的本地机器上构建良好.
触发构建定义时会发生此问题.构建运行并持续一段时间直到它到达Microsoft程序集引用.
命名
空间
"Microsoft" 中不存在类型或命名空间名称"Office "(您是否缺少
程序集引用?)
找不到类型或命名空间名称'Application'(您是否缺少using指令或程序集引用?)
等等
如果重要,引用路径指向GAC.
帮助会非常棒,因此您可以通过扩展来表现出色.
此致,Byron Cobb.
