php 格式化 DateTime 对象，尊重 Locale::getDefault()

Formatting DateTime object, respecting Locale::getDefault()

提问by stoefln

I have a DateTime object which I'm currently formating via

我有一个 DateTime 对象，我目前正在通过

$mytime->format("D d.m.Y")

Which gives me exactly the format I need:

这正是我需要的格式：

Tue 5.3.2012

2012 年 3 月 5 日星期二

The only missing point is the correct language. I need German translation of Tue(Tuesday), which is Die(Dienstag).

唯一缺少的一点是正确的语言。我需要Tue（Tuesday）的德文翻译，即Die（Dienstag）。

This gives me the right locale setting

这给了我正确的语言环境设置

Locale::getDefault()

But I don't know how to tell DateTime::formatto use it.

但我不知道如何告诉DateTime::format使用它。

Isn't there a way to do something like:

有没有办法做这样的事情：

$mytime->format("D d.m.Y", \Locale::getDefault());

You can use the Intlextension to format the date. It will format dates/times according to the chosen locale, or you can override that with IntlDateFormatter::setPattern().

您可以使用Intl扩展名来格式化日期。它将根据所选语言环境格式化日期/时间，或者您可以使用IntlDateFormatter::setPattern().

A quicky example of using a custom pattern, for your desired output format, might look like.

对于所需的输出格式，使用自定义模式的快速示例可能如下所示。

$dt = new DateTime;

$formatter = new IntlDateFormatter('de_DE', IntlDateFormatter::SHORT, IntlDateFormatter::SHORT);
$formatter->setPattern('E d.M.yyyy');

echo $formatter->format($dt);

Which outputs the following (for today, at least).

输出以下内容（至少在今天）。

Di. 4.6.2013

迪。4.6.2013

That's because formatdoes not pay attention to locale. You should use strftimeinstead.

那是因为format不注意语言环境。你应该strftime改用。

For example:

例如：

setlocale(LC_TIME, "de_DE"); //only necessary if the locale isn't already set
$formatted_time = strftime("%a %e.%l.%Y", $mytime->getTimestamp())
