How to use the Webman framework to achieve multi-language support and internationalization functions?

Webman is a lightweight PHP framework that provides rich functions and extensibility, allowing developers to develop Web applications more efficiently. Among them, multi-language support and internationalization functions are very important features in web applications, which can help us localize applications to adapt to the needs of users in different regions and languages. In this article, we will introduce how to use the Webman framework to achieve multi-language support and internationalization capabilities.

Configuration file preparation

First, we need to add relevant configurations for multi-language support and internationalization functions in the configuration file of the Webman framework. Open the config/app.php file and add the following code:

// 默认语言
'language' => 'zh_CN',

// 支持的语言列表
'languages' => [
    'zh_CN' => '中文',
    'en_US' => 'English',
],

// 语言资源文件目录
'language_path' => BASE_PATH . '/resources/lang',

In the above configuration, we set the default language to zh_CN and defined the supported Directory of language lists and language resource files. You can modify these configurations according to your needs.

Language resource file preparation

Next, we need to store translation strings for different languages in the language resource file. In the Webman framework, language resource files are located in the resources/lang directory.

We take Chinese as an example, add the following code in the resources/lang/zh_CN.php file:

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

Then, in resources/lang/en_US Add the following code to the .php file:

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

In the above code example, we have defined two different languages of hello and welcome. Version.

Using the translation function in the controller

Now, we can use the translation function in the controller to get the translated string. In the controller, the translated string can be obtained by calling the __() function.

<?php

namespace AppControllers;

use supportRequest;
use supportResponse;

class HomeController
{
    public function index(Request $request, Response $response)
    {
        $greeting = __('hello'); // 获取翻译后的字符串
        $welcomeMessage = __('welcome');
        
        return $response->html($greeting . ' ' . $welcomeMessage);
    }
}

In the above code example, we use the __() function to get the translated hello and welcome strings, and They are concatenated and returned to the user.

Using the translation function in the view

In addition to using the translation function in the controller, we can also use the translation function in the view file to convert the translated string displayed directly to the user.

<!DOCTYPE html>
<html>
<head>
    <title>多语言支持和国际化功能示例</title>
</head>
<body>
    <h1><?php echo __('hello'); ?></h1>
    <p><?php echo __('welcome'); ?></p>
</body>
</html>

In the above code example, we use the __() function to get the translated hello and welcome strings, and They are displayed in the h1 and p tags respectively.

Summary

Through the above steps, we successfully used the Webman framework to achieve multi-language support and internationalization functions. We set the supported language list and the directory of language resource files through the configuration file, and use the __() function in the controller and view to get the translated string. This allows our application to display translated content based on the user's language preference.

I hope this article can help you understand how to use the Webman framework to achieve multi-language support and internationalization functions. By properly using multi-language support and internationalization features, we can adapt applications to user needs in different regions and languages and improve user experience.
