How to use the Hyperf framework for international support

With the rapid development of globalization, many applications need to have multi-language support functions to meet the needs of different countries and needs of regional users. As a lightweight, high-performance framework, the Hyperf framework provides international support functions and can help developers quickly develop multi-language applications.

This article will introduce how to use internationalization functions in the Hyperf framework and provide corresponding code examples.

1. Configure multi-language support

First, you need to perform relevant configurations in the Hyperf configuration file config/autoload/i18n.php. You can use the php bin/hyperf.php vendor:publish hyperf/i18n command to copy the default configuration file to the config/autoload directory. Then make the following configuration in the i18n.php file:

return [
    // 默认的语言环境
    'locale' => 'zh_CN',
    // 语言文件的存放位置
    'fallback_locale' => 'en',
    // 支持的语言列表
    'locale_list' => [
        'zh_CN',
        'en',
    ],
    // 自动检测浏览器的语言设置
    'detect_locale' => true,
    // 语言文件的扩展名
    'ext' => '.php',
];

In the above configuration, locale is the default locale, fallback_locale is the current locale An alternative locale if the requested locale does not exist. locale_list Specifies the list of languages ​​supported by the project. detect_locale Set to true to automatically detect the browser's language setting. ext specifies the extension of the language file, the default is .php.

2. Write language files

Create the corresponding language folder in the resources/lang directory, and then create language files for different locales in the folder. For example, create two folders, zh_CN and en, to store Chinese and English language files respectively.

In each language file, you can define the key value corresponding to the translation content. For example, create the messages.php file under the zh_CN folder with the following content:

return [
    'welcome' => '欢迎使用Hyperf框架',
];

Create under the en folder messages.php file, the content is as follows:

return [
    'welcome' => 'Welcome to Hyperf framework',
];

3. Use language package

In the controller or service class, you can passHyperfUtilsApplicationContext::getContainer()-&gt ;get('translator') to obtain the translator (translator) instance, and then obtain the translation content of the corresponding locale through the translator's trans method.

<?php

namespace AppController;

use HyperfHttpServerAnnotationController;
use HyperfHttpServerAnnotationRequestMapping;
use HyperfHttpServerContractRequestInterface;
use HyperfUtilsApplicationContext;

/**
 * @Controller()
 */
class IndexController
{
    /**
     * @RequestMapping("/")
     */
    public function index(RequestInterface $request)
    {
        $translator = ApplicationContext::getContainer()->get('translator');
        
        // 获取当前语言环境
        $locale = $translator->getLocale();
        
        // 获取语言包中的翻译内容
        $welcome = $translator->trans('welcome');
        
        return [
            'locale' => $locale,
            'welcome' => $welcome,
        ];
    }
}

In the above code, use $translator->getLocale() to obtain the current locale. Then get the corresponding translation content through $translator->trans('welcome').

4. Switching the locale environment

In actual applications, it may be necessary to switch the locale environment according to the user's selection or other conditions. The Hyperf framework provides the HyperfUtilsContext class to implement context, and you can set the locale through Context::getContainer()->set('locale', $locale).

<?php

use HyperfUtilsContext;

// 切换到中文环境
Context::getContainer()->set('locale', 'zh_CN');

In the above code, set the locale to Chinese through set('locale', $locale).

Summary:

Through the above steps, we can successfully implement internationalization support functions in the Hyperf framework. First, you need to make relevant configurations in the configuration file, then write the language file, and use the translator in the code to obtain the translated content. You can use context to switch locales based on your needs.

Through the international support of the Hyperf framework, developers can easily implement multi-language applications and provide a better user experience for global users.

The above are the detailed steps and sample code for using the Hyperf framework for internationalization support. I hope to be helpful!
