Using Internationalization in ThinkPHP6

With the process of globalization, more and more websites and applications need to support multiple languages ​​in order to attract multinational users and customers. ThinkPHP6 provides powerful internationalization functions, allowing developers to easily implement multi-language support. This article will introduce the steps and techniques for using Internationalization in ThinkPHP6.

1. Configuring language package

In ThinkPHP6, language package is to classify all the text that needs to be translated in the application and save it to a specific file, so that our Apps can easily switch language versions. In the app.php file under the config directory, there is a 'lang_switch_on' option, which we set to true to enable the language pack feature.

'lang_switch_on' => true,

Next, we need to create a lang.php file in the config directory to configure our language pack. The sample content is as follows:

return [

'zh-cn' => [
    'name' => '姓名',
    'age' => '年龄',
    'email' => '邮箱'
],
'en-us' => [
    'name' => 'Name',
    'age' => 'Age',
    'email' => 'Email'
]

];

In the above code, we set two language versions in the language pack array: Chinese Simplified ('zh- cn') and English ('en-us'), each language version has its own translated text such as name ('name'), age ('age') and email address ('email').

2. Using the Lang helper function

Once the language package is configured, we can use the Lang helper function to reference the translated text in the application. The Lang helper function provides three parameters: the key name of the language package, the substitution variable, and the language version. The sample code is as follows:

//Get the current language version
$lang = Lang::getLangSet();

//Use the Lang helper function to get the translated text
echo Lang: :get('name', [], $lang);

In the above code, we first use the Lang::getLangSet() function to get the current language version, and then call the Lang::get() function to get the translated name text in the corresponding language version. Since we have no substitution variables, the second parameter is an empty array.

If we want to use the Lang helper function in the view file, we can use the following syntax:

{{$lang = Lang::getLangSet()}}
{ {$name = Lang::get('name', [], $lang)}}
{{$age = Lang::get('age', [], $lang)}}
{ {$email = Lang::get('email', [], $lang)}}

3. Implementing multi-language routing

In addition to using the Lang helper function to reference To translate text, we can also achieve multi-language support through routing. In order to implement multi-language routing, we must configure corresponding routing rules.

Use routing group (Route::group) with '/lang/:lang' as the prefix, where ':lang' represents the language version. The sample code is as follows:

Route::group(':lang', function () {

//这里写你的路由规则

})->ext('html')->pattern('lang' , '^[a-z]{2}-(?:[A-Z]{2})?$');

In the above code, we use ':lang' as the prefix and then define a regular expression to match the language version. Finally, set the 'ext' option to allow the route to support automatic suffix parsing, and set the 'pattern' option to limit the language version format.

When a user accesses '/', we can redirect them to the default language version of the route, such as '/zh-cn/home'. We can also set parameters in routing rules for better multi-language support. The sample code is as follows:

Route::get(':lang/home', 'home/index');

In the above code, we set a ':lang/home' routing rules, mapping it to the 'home/index' controller and action. In this way, when users access 'zh-cn/home' and 'en-us/home', they will be automatically routed to the corresponding controller operations.

Conclusion

Using Internationalization in ThinkPHP6, multi-language support can be easily achieved. By configuring language packs, using Lang helper functions and implementing multi-language routing, we can create a truly global application that attracts more users from different countries and regions.
