How to use ThinkPHP6 to achieve localized interaction

With the development of the Internet and the acceleration of globalization, more and more websites and applications need to be localized for interaction in different regions and languages. Localized interaction refers to adjusting the website or application to meet the needs of the user based on factors such as the language, culture, and habits of the country or region where the user is located. In this article, we will introduce how to use the ThinkPHP6 framework to achieve localized interaction.

1. Multi-language support

Multi-language support is the basis for localized interaction. The ThinkPHP6 framework provides a variety of multi-language support methods, and we can choose the appropriate method according to actual needs.

1. File-based multi-language support

File-based multi-language support is the most commonly used method. We can store translation files in different languages in different directories and achieve multi-language support by setting language packs.

First, create a lang.php file in the config directory to set the configuration items of the language package, as shown below:

 'zh-cn', // 扩展语言包 'extend_list' => [ 'zh-cn','en-us' ], ];

Description:

default_lang: Default Language pack.

extend_list: Extended language pack list.

Next, create the corresponding language pack directory in the app/lang directory. We take the Chinese language package as an example, create the zh-cn directory under the lang directory, and create a zh-cn under the directory. .php file, used to store key-value pairs corresponding to Chinese translation, as shown below:

 '你好', 'welcome' => '欢迎', ];

Create the en-us directory in the English language package, and create an en-us.php file in this directory , used to store the key-value pairs corresponding to English translation, as shown below:

 'Hello', 'welcome' => 'Welcome', ];

Finally, use the Lang class in the controller or view for translation, for example:

echo Lang::get('hello');

Through the above With these steps, we can implement multi-language support in our application.

2. Database-based multi-language support

In addition to file-based multi-language support, ThinkPHP6 also provides database-based multi-language support. This method achieves multi-language support by storing translation information in the database.

First, create a language table in the database to store translation information, as shown below:

CREATE TABLE `language` ( `id` int unsigned NOT NULL AUTO_INCREMENT, `name` varchar(50) NOT NULL COMMENT '翻译名称', `lang` varchar(10) NOT NULL COMMENT '语言包', `value` varchar(255) NOT NULL COMMENT '翻译内容', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

Then, create the lang.php configuration file in the config directory and set the language package to Database mode, as shown below:

 'db', // 默认语言 'default_lang' => 'zh-cn', // 数据表名 'table_name' => 'language', ];

Description:

type: Language package type, here set to database mode.

default_lang: Default language.

table_name: The name of the data table that stores translation information.

Finally, just use the Lang class in the controller or view for translation, for example:

echo Lang::get('hello');

Through the above steps, we can use the database to store translation information in the application to achieve multiple language support.

2. Localized interaction

In addition to multi-language support, ThinkPHP6 also provides a series of localized interactive functions for adjustment to different regions and languages. The following are several commonly used localized interactive functions:

1. date_format()

date_format() function is used to format date and time. The format of time and date may also change when the application is run in different regions and locales. Therefore, it is very necessary to use the date_format() function to format dates and times in your application.

For example, the following code will format the current time into the form of "year-month-day hour:minute:second":

$date = date('Y-m-d H:i:s'); echo date_format(date_create($date), 'Y-m-d H:i:s');

2. number_format()

The number_format() function is used to format numbers. Different countries and regions have different number formats, and you can use the number_format() function to format them as needed. For example:

$num1 = 1234567.89; $num2 = 9876543.21; echo number_format($num1, 2, '.', ','); echo number_format($num2, 2, '.', ',');

The output result is:

1,234,567.89 9,876,543.21

3. setlocale()

The setlocale() function is used to set localization-related environment variables. For example, we can use the setlocale() function to set the date and time format, currency symbol, number format, etc. For specific content, please refer to the relevant instructions in the PHP manual. For example:

setlocale(LC_TIME, 'en_US.UTF8'); echo strftime("%b %d %Y %H:%M:%S");

The above code will output the date and time in the format of "Jan 01 2022 00:00:00".

Through the above methods, we can achieve localized interaction under the ThinkPHP6 framework and provide a better experience for users in different regions and languages.
