编程多语言PHP应用程序 [英] Programming Multi-Language PHP applications

问题描述

我正在开发一个PHP应用程序，我想知道在其他国家/地区为用户提供多语言支持的最佳方法。

我精通使用PHP，但从来没有开发任何支持其他语言的东西。

我正在考虑将语言放入带有常量的PHP文件中，例如：

en.php可以包含：

  define（'HZ_DB_CONN_ERR'，'有一个错误连接到数据库。 
  

和fr.php可能包含：

  define（'HZ_DB_CONN_ERR'，'无论法语为上述...'）; 
  

然后我可以调用函数并自动传递正确的语言。

  hz_die（'HZ_DB_CONN_ERR'，$ this）; 
  

这是一个很好的方式吗？

解决方案

很奇怪人们似乎忽视了明显的解决方案。您的具体地区特定文件的想法很好。有en.php：

  define（'LOGIN_INCORRECT'，'你的登录信息不正确'）; 
 ... 
  

然后，假设你有一个全局配置/常量文件'd建议有很多原因），有这样的代码：

  if（$ language =='en'）{
 reqire_once'en.php'; 
} else if（$ language =='de'）{
 require_once'de.php'; 
} 
  

您可以定义数字和货币显示，比较/排序（即德语，法语和英语都有不同的排序规则方法）等。

人们经常忘记PHP是一种动态语言，所以这样的事情：

  if（$ language =='en'）{
 function cmp（$ a，$ b）{...} 
} else if（$ language =='de'）{
 function cmp（$ a，$ b）{...} 
} 
  

其实是完全合法的。使用它们。

I'm developing a PHP application and I'm wondering about the best way to include multi-language support for users in other countries.

I'm proficient with PHP but have never developed anything with support for other languages.

I was thinking of putting the language into a PHP file with constants, example:

en.php could contain:

define('HZ_DB_CONN_ERR', 'There was an error connecting to the database.');

and fr.php could contain:

define('HZ_DB_CONN_ERR', 'whatever the french is for the above...');

I could then call a function and automatically have the correct language passed in.

hz_die('HZ_DB_CONN_ERR', $this);

Is this a good way of going about it?

解决方案

Weird. People seem to be ignoring the obvious solution. Your idea of locale-specific files is fine. Have en.php:

define('LOGIN_INCORRECT','Your login details are incorrect.');
...

Then, assuming you have a global config/constants file (which I'd suggest for many reasons), have code like this:

if ($language == 'en') {
  reqire_once 'en.php';
} else if ($language == 'de') {
  require_once 'de.php';
}

You can define functions for number and currency display, comparison/sorting (ie German, French and English all have different collation methods), etc.

People often forget PHP is a dynamic language so things like this:

if ($language == 'en') {
  function cmp($a, $b) { ... }
} else if ($language == 'de') {
  function cmp($a, $b) { ... }
}

are in fact perfectly legal. Use them.
