Multi-language support and internationalization processing of PHP and mini-programs

The popularity and popularity of mini-programs has made developers pay more and more attention to user experience, especially in terms of multi-language support and internationalization processing. In this article, we will explore how to use PHP and the applet framework to achieve multi-language support and internationalization processing.

1. The need for multi-language support

With the development of the Internet, more and more applications need to support multi-language users in order to attract more user groups. Especially for small programs, multi-language support can help developers better meet the needs of global users.

2. Multi-language support for mini programs

In mini programs, multi-language support can be achieved by introducing language files into the mini program code. First, we need to create a languages ​​folder in the root directory of the applet, and create language files in different languages ​​under this folder, such as en.json and zh.json.

Then, add the language support field in the global configuration file app.json of the mini program, as shown below:

{
  "lang": "en"
}

Next, introduce the language in the app.js file of the mini program file, and load the corresponding language file according to the current language, as shown below:

const lang = require('languages/' + app.globalData.lang + '.json')
App({
  globalData: {
    lang: 'en',
    ...
  },
  onLaunch: function() {
    wx.setStorageSync('lang', this.globalData.lang)
    ...
  },
  ...
})

Through the above steps, we can achieve multi-language support in the mini program. In other pages of the mini program, we can obtain text content in different languages ​​through the language objects in the app.js file.

3. Multi-language support of PHP

In PHP, multi-language support can be achieved by creating language files and loading the corresponding language files by obtaining the user's language preferences. First, we need to create a languages ​​folder in the PHP project and create language files in different languages ​​under this folder, such as en.php and zh.php.

Then, we can set the default language in the PHP configuration file, as shown below:

<?php
  $default_lang = 'en';
?>

Next, in the PHP code, we can get the user's language preference or front-end Use the passed language parameter to determine the current language and load the corresponding language file, as shown below:

<?php
  $lang = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
  if (strpos($lang, 'en') !== false) {
    include('languages/en.php');
  } else if (strpos($lang, 'zh') !== false) {
    include('languages/zh.php');
  } else {
    include('languages/en.php');
  }
?>

Through the above steps, we can achieve multi-language support in the PHP project. In other code in PHP, we can obtain text content in different languages ​​through loaded language files.

4. Internationalization processing with multi-language support

In addition to supporting multiple languages, internationalization processing is also an important requirement. International processing mainly includes processing of date format, time format, currency format, etc. In mini programs and PHP, we can use corresponding functions to implement internationalization processing.

In the applet, we can use the wx.navigateToLocaleDate function to convert the date format to the local date format of the current locale.

In PHP, we can use the strftime function to convert the date format to the local date format of the current locale.

The internationalization processing of small programs and PHP can use corresponding functions and methods according to specific needs.

Conclusion

In this article, we introduced how to use PHP and the applet framework to achieve multi-language support and internationalization processing. By introducing language files and loading corresponding language files according to the user's language preferences, we can achieve multi-language support. Internationalization processing can be achieved through corresponding functions and methods. When developing applications, we should choose appropriate methods and tools based on user needs to achieve multi-language support and internationalization to improve user experience and meet user needs.
