How to use ThinkPHP6 for multi-language management?

With the development of globalization, more and more websites and applications need to provide multi-language support to meet the needs of users with different language and cultural backgrounds. When using ThinkPHP6 for application development, how to manage multi-language is an important issue. This article will introduce how to use ThinkPHP6 for multi-language management to help developers better implement multi-language support.

1. Basics of multi-language management

Multi-language management is to translate the text information in the application through specific technical means, and dynamically load the corresponding translated text according to the user's language settings. In order to achieve the purpose of supporting multiple languages ​​when the application is displayed in front of users.

In ThinkPHP6, the implementation of multi-language management is based on language pack. A language pack is a file in PHP used to store the correspondence between keywords and translated text. When the application needs to translate text, it looks up the corresponding translated text from the language pack to dynamically generate the user interface.

2. Create a language pack file

In order to use ThinkPHP6 for multi-language management, you first need to create a language pack file. There are two ways to create language pack files.

1. Manual creation

The steps to manually create a language pack file are as follows:

(1) Create a new lang directory in the root directory

(2) Create a new zh-cn directory under the lang directory, zh-cn here is the name of the language package

(3) Create a new folder upload under the zh-cn directory, upload here represents the application The name of the controller folder that needs to be translated

(4) Create a .php file in the upload directory, such as test.php

(5) Define the need for translation in test.php Keywords and corresponding translated text, for example:

return [

'hello' => '你好',

]

where hello is the keyword, and hello is the corresponding translated text. When the hello keyword needs to be translated in the application, the application will automatically load the translated text.

2. Command line creation

ThinkPHP6 provides a command line tool for quickly creating language pack files. Use this tool to quickly create language pack files.

The specific command is as follows:

php think lang:build zh-cn upload

Among them, zh-cn represents the name of the language package, and upload represents the controller that needs to be translated. Folder name. After executing this command, a language pack file required by all controllers in the controller folder will be automatically created.

3. Use language packs to achieve multi-language management

After creating the language pack file, you can use the language pack in the application to achieve multi-language management.

1. Translation Keywords

When you need to translate keywords in the application, you can use the lang() function to obtain the corresponding translation text. The syntax format of the lang() function is as follows:

lang('keyword')

where the keyword is the keyword defined in the language pack file.

For example, a variable is defined in the controller:

$data['hello'] = 'hello';

When you need to translate the value of the variable, you can Use the lang() function to get the corresponding translation text:

$data['hello'] = lang('hello');

In this way, when the application loads, it will automatically Read the corresponding translated text from the language pack.

2. Switch language pack

When switching language packs in the application, you can use the system configuration item lang to set the currently used language pack. The method is as follows:

(1) Create a lang.php file in the config folder of the application

(2) Define the currently used language package in lang.php, for example:

return [

'default_lang' => 'zh-cn',

];

The default_lang here is the system configuration item, indicating the default language pack.

(3) You can use the config() function in the controller to obtain system configuration items. For example:

$lang = config('lang.default_lang');

In this way, you can dynamically obtain the default language package of the current system.

4. Summary

Multi-language management is a technology widely used in global application development. When using ThinkPHP6 for application development, it is a feasible solution to achieve multi-language management by creating language pack files and using language packs. This article introduces the specific steps to create language pack files and use language packs to achieve multi-language management. I hope it will be helpful to the majority of developers.
