ThinkPHP6 multi-language switching: realizing international applications

With the rapid development of the Internet and the process of globalization, more and more websites and applications need to be supported Multi-language capabilities to meet the needs of users in different countries and regions. When using ThinkPHP6 to develop web applications, achieving multi-language switching is an important task. This article will introduce how to implement international applications in ThinkPHP6 to provide users with a convenient multi-language experience.

Why do you need to switch to multiple languages?

In the context of globalization, users have diverse needs for using the Internet, and language is an important barrier. Users prefer to use a language they are familiar with to browse websites and applications, and by using a language they are familiar with, user satisfaction and loyalty can be increased. Therefore, in order to meet the needs of users of different languages, the multi-language switching function has become very important.

ThinkPHP6 multi-language configuration

In ThinkPHP6, multi-language switching can be achieved through configuration files. First, create a lang.php file in the config directory to store multi-language configuration information. In the lang.php file, we can define key-value pairs for various languages, for example:

return [
    'en' => 'English',
    'zh-cn' => '简体中文',
    'ja' => '日本語',
];

The above code defines three languages: English, Simplified Chinese and Japanese. The key name is the language identifier and the value is Language name.

Multi-language switching in the controller

In ThinkPHP6, the currently used language can be obtained through the configuration file. First, reference the multi-language class library in the controller:

use thinkacadeLang;

Then, use the following code in the method to get the current language:

$locale = Lang::getLangSet();

The currently used language identifier can be obtained through the above code , such as 'en', 'zh-cn', etc.

Using the lang method of the Lang class can dynamically obtain the value in the corresponding language file. For example, we can display different welcome messages according to the user's language selection:

$message = Lang::get('welcome');

The value of the 'welcome' key is defined in the multi-language configuration file. According to the user's selection, the value in the corresponding language file will be returned. .

Multi-language switching in view templates

In ThinkPHP6, multi-language switching in view templates is also very convenient. Using the range method of the Lang class, different display texts can be dynamically switched according to the user's selection. For example:

<span class="lang">{{ Lang::range('welcome') }}</span>

The above code will dynamically display different welcome messages according to the language selected by the user.

Multi-language switching in URL

In ThinkPHP6, we can achieve multi-language switching through parameters in the URL. First, define multi-language routing rules in the routing configuration:

return [
    'lang/[:lang]' => 'index/index/index',//设置语言路由
];

The above code defines a routing rule with the parameter lang, for example, /lang/en means switching to English, /lang/zh-cn means switching to Simplified Chinese.

Then, in the controller, get the language selected by the user through the following code and set it as the current language:

$lang = $this->request->param('lang');
Lang::setLangSet($lang);

Through the above code, you can get the lang parameter in the URL and set it Set as current language.

Multi-language switching in the database

In ThinkPHP6, we can also store multi-language data through the database to achieve dynamic switching of multiple languages. First, create a corresponding multi-language table in the database, such as the lang table, which contains multiple fields, such as id, lang, value, etc.

Then, in the controller, the data is queried from the database according to the language selected by the user and passed to the view template:

$data = LangModel::where('lang', $locale)->select();
$this->assign('data', $data);

Through the above code, the queried multi-language data can be passed to View template is displayed.

Summary

Multi-language switching is very important for international applications and can help websites and applications better meet the needs of users around the world. In ThinkPHP6, through the cooperation of configuration files, controllers, view templates and databases, the multi-language switching function can be easily realized. Developers can choose the appropriate method according to their actual needs to achieve multi-language switching, improve user experience, and expand the audience range of applications.
