ThinkPHP6 multi-language support: realizing multi-language applications

Introduction:
With the development of globalization, more and more applications need to support multi-language Function. In web development, we often need to transform interface text, prompt information and other content according to the user's language environment. The ThinkPHP6 framework provides powerful multi-language support, allowing us to easily implement multi-language applications. This article will introduce how to configure and use multi-language features in ThinkPHP6, and illustrate it with code examples.

1. Configure multi-language support
First, we need to make the corresponding configuration in the project configuration file config/app.php. Find the app_namespace attribute and add 'default_lang' => 'zh-cn', 'lang_switch_on' => true, after it. Among them, 'default_lang' represents the default language, which we set to Simplified Chinese. 'lang_switch_on' means turning on the language switching function.

Next, we need to create a lang folder under the config directory, and create a zh-cn.php# under this folder ## file, used to store the Chinese simplified language pack. In the zh-cn.php file, we can define various key-value pairs for text translation in different language environments. For example:

return [
    'welcome' => '欢迎使用ThinkPHP6',
    'hello'   => '你好',
];

2. Language switching

In multi-language applications, users can switch according to their own language preferences. In order to implement the language switching function, we need to add the following code to the controller:

use thinkacadeLang;

public function switchLang($lang)
{
    Lang::setLang($lang);
    return redirect()->back();
}

In the template file, we can use the keys defined in the language package to display text in different locales. For example, we can use

lang('hello') to get the "Hello" text in the corresponding language. The entire code example is as follows:

use thinkacadeLang;

public function index()
{
    echo lang('welcome');
    echo lang('hello');
}

public function switchLang($lang)
{
    Lang::setLang($lang);
    return redirect()->back();
}

3. Language package extension

In the above example, we only created the Chinese Simplified language package. However, some applications may need to support multiple languages. In order to expand the language pack, we only need to create language pack files for other languages ​​under the
lang folder. For example, we can create a en-us.php file under the lang folder to store the English language pack. In the en-us.php file, we can define the same key as the Chinese language pack, but the value is the corresponding English text. For example:

return [
    'welcome' => 'Welcome to ThinkPHP6',
    'hello'   => 'Hello',
];

In this way, when the user selects the English locale, the application will display the text content in English.

End:

Through the above examples, we learned how to configure and use the multi-language support function in ThinkPHP6. Through simple configuration and language pack expansion, we can easily implement multi-language applications and provide users with a more friendly and convenient user experience. In future development, we can further expand and customize multi-language functions based on actual needs to meet the needs of different user groups. I hope this article will be helpful to your learning and development.
