不论什么时候 Zend_Date
方法需要参数 $parts
,下面常数中其中之一可担当此任,
用来选择日期的特定部分或指示日期使用的或期望使用的格式(例如 RFC 822)。
例如,常数 Zend_Date::HOUR
可以像下列所示来使用。当和星期几、日期、小时、分钟、秒和任何其它因位于世界不同的地方而不同地表示的日期部分一起使用时,
对象的时区将自动用来计算当前值,即使是内部的时间戳和此刻一致并且不论用户的地理位置在世界的何方。
不管使用了哪些单元,输出必需表达为 GMT/UTC 或本地化。下面的输出例子反映了 Europe/GMT+1 hour (e.g. Germany, Austria, France) 的本地化。

如果你需要的日期格式没有在上述的格式中出现,那么使用从下面 ISO 格式指定器产生的自定义格式。 下面的例子示例了从下列表中生成的自定义 ISO 格式的常量的用法。格式长度无限制。并且允许格式常量的多重用法。
如果你喜欢的话,可接受的格式指定器可以从 ISO 格式修改为 PHP 的日期格式,然而,PHP 日期格式指定不支持所有的按 ISO 标准定义的格式。
使用 Zend_Date::setOptions(array('format_type' => 'php'))
方法来把 Zend_Date 方法从支持 ISO 格式制定器切换到 PHP date()类型制定器(参见下面 第 12.6.4 节 “ 使用 PHP 的 date() 格式指定器的自定义输出格式 ”)。
例 12.15. 自定义 ISO 格式用法示例
$locale = new Zend_Locale('de_AT'); $date = new Zend_Date(1234567890, false, $locale); print $date->toString("'Era:GGGG='GGGG, ' Date:yy.MMMM.dd'yy.MMMM.dd");

注意 | |
---|---|
注意缺省的 ISO 格式不同于 PHP 的格式,如果在先前没有使用,PHP 的格式可以迭代。 特别是 Year and Minute 的格式指定器不常按预期来使用。 对于 year 有两个可用的指定器经常发生错误: ISO 年的Y 指定器和真实年的 y 的指定器。 区别微小但意义重大。 Y 计算 ISO 年,常用于日历格式,例如 the 31. December 2007。 真实年为 2007,但它是 2008 年的第一周的第一天,所以,如果使用 'dd.MM.yyyy' 会得到 '31.December.2007' 但如果使用 'dd.MM.YYYY' 会得到 '31.December.2008'。 正如你所看到的,这不是 bug , 但期望的行为依赖指定器的使用。 对 minute 来说区别不大。ISO 使用 m 指定器,PHP 使用 i。 所以如果没有按你的格式获得分钟数,检查是否使用了正确的指定器。 |
如果你更喜欢使用 PHP 的日期格式指定器,可以使用 Zend_Date::setOptions(array('format' => 'php'))
方法
把 Zend_Date 方法从支持 ISO 格式制定器切换到 PHP date()类型制定器。然后所有参数必需用 PHP's date()
格式指定器 给出。
PHP 日期格式缺乏一些 ISO 格式支持的格式,反之亦然。如果不喜欢,可以使用标准的 ISO 格式。
而且,如果你有一些历史遗留的使用 PHP 日期格式的代码,可以用 Zend_Locale_Format::convertPhpToIsoFormat() 手工转换为 ISO 格式,或使用 setOptions()
。
下面的例子示例了从下表生成的自定义格式的常量的用法。
例 12.16. 用 PHP 指定器自定义格式的用例
$locale = new Zend_Locale('de_AT'); Zend_Date::setOptions(array('format_type' => 'php')); $date = new Zend_Date(1234567890, false, $locale); // outputs something like 'February 16, 2007, 3:36 am' print $date->toString('F j, Y, g:i a'); print $date->toString("'Format:D M j G:i:s T Y='D M j G:i:s T Y");
下标列出了带有相应等同的 Zend_Date常量和 CLDR/ISO 格式指定器的 PHP 日期格式指定器。
对一些情况,当 CLDR/ISO 格式没有等同的格式指定器时,PHP 格式指定器不用 Zend_Locale_Format::convertPhpToIsoFormat()
来改变,
并且 Zend_Date 方法承认这些 “奇特的” PHP 格式指定器,即使是处于缺省的 "ISO" 格式模式中。
