Using PHP to develop multi-language translation and internationalization of small programs

Introduction: With the development of the information age, people are increasingly dependent on the mobile Internet, and small programs are an important part of the mobile Internet. , is being widely used. However, when developing small programs, how to achieve multi-language translation and internationalization has become an important consideration. This article will introduce the method of using PHP to develop multi-language translation and internationalization of small programs, and give corresponding code examples.

1. The Importance of Multilingual Translation and Internationalization

With the internationalization trend of mini programs, users come from different countries and regions and use different languages. If a mini program only supports one language, it will lose many potential users. Therefore, multilingual translation and internationalization are essential. By translating the text content of the mini program into multiple languages ​​and dynamically loading the corresponding text content according to the user's language preference, the user experience can be improved and user stickiness can be increased.

2. Use PHP to achieve multi-language translation and internationalization

1. Create language files

First, we need to create multiple language files, each The file corresponds to a language. In the language file, we define some constants, each constant corresponds to a text content. For example, we create two language files: zh-cn.php and en.php. Among them, zh-cn.php corresponds to Chinese, and en.php corresponds to English.

// zh-cn.php
<?php
define('HELLO', '你好');
define('WELCOME', '欢迎');

// en.php
<?php
define('HELLO', 'Hello');
define('WELCOME', 'Welcome');

2. Load the corresponding language file according to the user's language preference

When the user accesses the mini program, we need to load the corresponding language file according to the user's language preference so that The corresponding text content is displayed in the mini program. Assuming that we obtain the user's language preference through a GET request, the corresponding language file can be loaded as follows.

$lang = 'zh-cn'; // 假设用户的语言偏好为中文
if ($_GET['lang']) {
    $lang = $_GET['lang'];
}

// 加载对应的语言文件
if ($lang === 'zh-cn') {
    require_once('zh-cn.php');
} elseif ($lang === 'en') {
    require_once('en.php');
}

3. Using the translated text content in the mini program

In the mini program, we can use the translated text content through the corresponding constants. For example, if we display a welcome message in the applet, we can directly use the constant WELCOME.

echo WELCOME; // 输出中文：欢迎

3. Summary

This article introduces the method of using PHP to develop multi-language translation and internationalization of small programs, and gives corresponding code examples. By dynamically loading the corresponding language files and using the translated text content in the mini program, multi-language translation and internationalization of the mini program can be achieved, improving user experience and increasing user stickiness. I hope this article will be helpful to everyone when developing small programs.
