在PHP和数字格式中将setlocale设置为fr-FR [英] setlocale to fr-FR in PHP and number formatting

问题描述

我正在尝试为我的网站之一创建法语版本.我已经在页面顶部设置了setlocale(LC_ALL, 'fr_FR');，并使用strftime正确地以法语显示了日期.

I am trying to create a French version of one of my sites. I have set setlocale(LC_ALL, 'fr_FR'); at the top of my page, and using strftime I am displaying dates correctly in the French style.

但是我在电话号码方面遇到了一些问题.页面的一部分使用了从Web服务获取的数据.我正在将返回值分配给这样的var:

However I am having some problems with a number. Part of the page uses data I am getting from a Web Service. I am assigning a returned value to a var like this:

$overallRating = $returnArray['Overall'];

然后我将使用下面的代码将其格式化为小数点后一位

I am then using the following code later to format it to 1 decimal place

number_format($overallRating,1)

在英文版中，totalRating值可能是7.5，并返回诸如7.5的值(通过number_format运行它的原因是，如果它返回7，我希望它显示7.0)

In the English version the overallRating value might be 7.5 and returns a value such as 7.5 (the reason for running it through the number_format is if it returns 7 I want it to display 7.0)

但是在法语版本中，如果我打印出原始的$ overallRating值，则会得到7,5，看起来它已经将其翻译为法语.这样做会很好，但是如果我通过number_format运行它，则会收到错误消息:

However in the French version if I print out the raw $overallRating value I get 7,5 which looks like it has translated it into french. This would be fine but if I run it through number_format I get the error:

Notice: A non well formed numeric value encountered in /sites/index.php  on line 250

第250行是number_format行

我认为对7,5的翻译搞砸了，但是不确定如何解决这个问题...

I presume the translation to 7,5 is messing it up, but not sure how to solve this...

使用PHP 5.3以防有什么新东西对我有帮助

推荐答案

因此，经过大量研究，最终找到了答案.

So eventually found the answer after a lot of research.

PHP只能与标准的美国十进制分隔符一起使用，而不能与法语的分隔符配合使用.

PHP only really works with standard US decimal seperators and can't cope with the french , seperator.

答案虽然不是十全十美，但可以重置数值以使用美国，同时允许日期等以法语设置格式.放置此行:

The answer, although not perfect is to reset numeric values to use US while allowing dates etc to be formatted in French. Placing this line:

 setlocale(LC_NUMERIC, 'C');

下

 setlocale(LC_ALL, 'fr_FR'); 

已经完成了窍门
