编写多语言 PHP 应用程序

2022-01-18 00:00:00 web-applications internationalization php

我正在开发一个 PHP 应用程序，我想知道为其他国家/地区的用户提供多语言支持的最佳方式.

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

我精通 PHP，但从未开发过任何支持其他语言的东西.

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

我正在考虑将语言放入带有常量的 PHP 文件中，例如:

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

en.php 可能包含:

en.php could contain:

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

并且 fr.php 可能包含:

and fr.php could contain:

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

然后我可以调用一个函数并自动传入正确的语言.

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

hz_die('HZ_DB_CONN_ERR', $this);

这是一个好方法吗?

推荐答案

奇怪.人们似乎忽略了明显的解决方案.您对特定于语言环境的文件的想法很好.有en.php:

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.');
...

然后，假设您有一个全局配置/常量文件(我建议有很多原因)，有这样的代码:

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';
}

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方法)等功能.

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

人们经常忘记 P​​HP 是一种动态语言，所以像这样:

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) { ... }
}

实际上是完全合法的.使用它们.

are in fact perfectly legal. Use them.
