PHP and UniApp realize data internationalization and multi-language support

As the globalization process accelerates, multi-language support becomes more and more important in software development. For a piece of software, internationalizing the user interface and displayed data can improve user experience, expand market scope, and meet users' multilingual needs. This article will introduce how to use PHP and UniApp to implement data internationalization and multi-language support, and provide relevant code examples.

1. PHP implements multi-language support

1. Create language pack file

First, we need to create a language pack file, which contains each language The corresponding translated text. Arrays can be used to store these texts, an example is as follows:

// language.php

$lang = array(
    'en' => array(
        'welcome' => 'Welcome',
        'hello' => 'Hello',
    ),
    'zh' => array(
        'welcome' => '欢迎',
        'hello' => '你好',
    ),
);

In the above example, we have created a language pack containing English and Chinese translated texts.

2. Select the corresponding language package according to the user's language settings

Next, we need to select the corresponding language package according to the user's language settings for display. You can use $_SERVER['HTTP_ACCEPT_LANGUAGE'] to obtain the user's language settings. An example is as follows:

$acceptedLanguages = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
$defaultLang = 'en'; // 默认语言为英语

$selectedLang = $defaultLang;
if (strpos($acceptedLanguages, 'zh') !== false) {
    $selectedLang = 'zh'; // 如果用户的语言设置中包含'zh'，则选择中文语言包
}

In the above example, we look for whether 'zh' is included in the user's language settings, and if so, select the Chinese language pack, otherwise select the English language pack.

3. Use the selected language pack

Once the language pack is selected, we can display the corresponding text according to the selected language pack. The example is as follows:

$language = $lang[$selectedLang];

echo $language['welcome']; // 根据选择的语言包输出对应的欢迎文本
echo $language['hello']; // 根据选择的语言包输出对应的你好文本

In the above example, we output the corresponding welcome text and hello text through the selected language package.

2. UniApp implements multi-language support

UniApp is a cross-platform development framework that can be written once and released on multiple terminals at the same time. The following will describe how to implement multi-language support in UniApp.

1. Create a language pack file

Similar to PHP, we need to create a language pack file that contains the translation text corresponding to each language. These texts can be stored using JSON format, an example is as follows:

// language.json

{
    "en": {
        "welcome": "Welcome",
        "hello": "Hello"
    },
    "zh": {
        "welcome": "欢迎",
        "hello": "你好"
    }
}

In the above example, we have created a JSON language pack containing English and Chinese translated text.

2. Select the corresponding language package according to the user's language settings

In UniApp, you can use uni.getSystemInfo to obtain the user's language settings. An example is as follows:

uni.getSystemInfo({
    success(res) {
        const acceptedLanguages = res.language;
        const defaultLang = 'en'; // 默认语言为英语
    
        let selectedLang = defaultLang;
        if (acceptedLanguages.indexOf('zh') !== -1) {
            selectedLang = 'zh'; // 如果用户的语言设置中包含'zh'，则选择中文语言包
        }
    }
});

In the above example, we obtain the user's language settings and select the corresponding language pack.

3. Use the selected language pack

Once the language pack is selected, we can display the corresponding text according to the selected language pack. The example is as follows:

const lang = require('./language.json');

console.log(lang[selectedLang]['welcome']); // 根据选择的语言包输出对应的欢迎文本
console.log(lang[selectedLang]['hello']); // 根据选择的语言包输出对应的你好文本

In the above example, we output the corresponding welcome text and hello text through the selected language package.

Summary

Through the multi-language support of PHP and UniApp, we can easily achieve data internationalization and multi-language support to provide users with a better experience. During the development process, please make sure to prepare the corresponding language pack, dynamically select the corresponding language pack according to the user's language settings, and use the selected language pack to display the corresponding text.

The above is the relevant content of PHP and UniApp to achieve data internationalization and multi-language support. I hope it will be helpful to you.
