You could use the HTTP_ACCEPT_LANGUAGE server variable to guess their locale and expected number format. 

If I were to implement this, I'd allow a user to set a preference to override the guessed, and my function would look like this:

<pre><code>function number_format_locale($number,$decimals=2) {
 $locale = ( isset($_COOKIE['locale']) ? 
 $_COOKIE['locale'] : 
 $_SERVER['HTTP_ACCEPT_LANGUAGE']
 )
 switch($locale) {
 case 'en-us':
 case 'en-ca':
 $decimal = '.';
 $thousands = ',';
 break;
 case 'fr':
 case 'ca':
 case 'de':
 case 'en-gb':
 $decimal = ',';
 $thousands = ' ';
 break;
 case 'es':
 case 'es-mx':
 default:
 $decimal = ',';
 $thousands = ' ';
 }
 return $number_format($number,$decimals,$decimal,$thousands);
}
</code></pre>

blocks|key|1438026|text|如果你正在部署一个本地化的网站，你会想要确保你的setlocale()。为了模仿yaauie的上述帖子，我会在初始化代码中添加类似以下代码片段的内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1438027|$locale+=+(+isset($_COOKIE['locale'])+)+?+
++++++++++++$_COOKIE['locale']+:+
++++++++++++$_SERVER['HTTP_ACCEPT_LANGUAGE'];
setlocale(LC_ALL,+$locale);|code-block|syntax|javascript|1438028|然后我们修改上面的函数number_format_locale()，如下所示：|style|CODE|1438029|function+number_format_locale($number,$decimals=2)+{
++++$locale+=+localeconv();
++++return+number_format($number,$decimals,
+++++++++++++++$locale['decimal_point'],
+++++++++++++++$locale['thousands_sep']);
+}|1438030|当然，这是在理想的情况下，根据您部署到的平台，以及您安装的语言环境文件的版本，您可能必须绕过一些不规范的地方进行编码。但是，设置语言环境将有助于处理金钱、数字和日期。|1438031|entityMap|0|LINK|mutability|MUTABLE|url|http://php.net/setlocale^0|O|B|0|0|0|B|M|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@$A|Z|B|10|1|11]]|C|$]]|$1|D|3|E|5|F|7|12|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|13|8|@$A|14|B|15|K|L]]|9|@]|C|$]]|$1|M|3|N|5|F|7|16|8|@]|9|@]|C|$G|H]]|$1|O|3|P|5|6|7|17|8|@]|9|@]|C|$]]|$1|Q|3|-4|5|6|7|18|8|@]|9|@]|C|$]]]|R|$S|$5|T|U|V|C|$W|X]]]]

If you're deploying a localized website, you're going to want to make sure you <a href="http://php.net/setlocale" rel="noreferrer" title="setlocale&#40;&#41;">setlocale()</a>. To riff off of yaauie's above post I'd add something like the following code snippet in your initialization code:

<pre><code>$locale = ( isset($_COOKIE['locale']) ) ? 
 $_COOKIE['locale'] : 
 $_SERVER['HTTP_ACCEPT_LANGUAGE'];
setlocale(LC_ALL, $locale);
</code></pre>

Then we modify the above function <code>number_format_locale()</code>, to look like so:

<pre><code>function number_format_locale($number,$decimals=2) {
 $locale = localeconv();
 return number_format($number,$decimals,
 $locale['decimal_point'],
 $locale['thousands_sep']);
 }
</code></pre>

Of course that's in an ideal world, depending on the platform you deploy to, and what version of the locale files you have installed, you might have to code around some irregularities. But setting locale is going to help with money, numbers, and dates.

print $number;

blocks|key|1652746|text|同时，PHP提供了一个NumberFormatter类，它非常适合于此目的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1652747|http://php.net/manual/de/class.numberformatter.php|offset|length|1652748|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|1E|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@$D|O|E|P|1|Q]]|A|$]]|$1|F|3|-4|5|6|7|R|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|C]]]]

I want to format the number 3253454 for my website visitors.

If I use the inbuilt number_format function, I get: 3,253,454 which is great for UK and USA, however most other countries use 3.253.454

I have many international visitors.

Can anyone give me a pointer to the best practice here?

Ideally I wish to get the browser's locale and format the number accordingly. Is this even possible in PHP?

PHP: Locale aware number format

服务器

我想为我的网站访问者格式化数字3253454。如果我使用内置的number_format函数，我会得到: 3,253,454，这对英国和美国来说很棒，但大多数其他国家使用的是3.253.454我有很多国际访客。有人能给我一个最佳实践的指点吗？理想情况下，我希望获得浏览器的区域设置，并相应地格式化数字。在PHP中这是可能...
