Teach you to use EasyWeChat and PHP to build multi-language support for WeChat mini programs

With the rise of WeChat mini programs, more and more developers are beginning to pay attention to and use WeChat mini programs. Multi-language support is an important and essential feature during development. This article will teach you how to use EasyWeChat and PHP to build multi-language support for WeChat mini programs.

1. Introduction to EasyWeChat
EasyWeChat is a WeChat development toolkit based on PHP. It provides a rich and easy-to-use interface to help us quickly develop WeChat-related functions. By using EasyWeChat, we can easily manage users, messages, payments and other functions of WeChat mini programs.

2. Implementation of multi-language support
In order to achieve multi-language support for WeChat mini programs, we need to carry out the following steps:

1. Prepare language files
   First , we need to prepare text content in different languages ​​and save it in the corresponding language files. These language files can be in JSON format or array format. For example: the Chinese language file (zh-CN.json) is as follows:

{
"hello": "Hello",
"welcome": "Welcome"
}

The English language file (en-US.json) is as follows:

{
"hello": "Hello",
"welcome": "Welcome"
}

2. Configuring multi-language support
   Add multi-language support configuration items in the EasyWeChat configuration file, as shown below:

'languages' => [
'zh-CN' => 'Simplified Chinese',
'en-US' => 'English'
]

3. Get the user language Settings
   In the WeChat applet, we can obtain the user's language settings through the following code:

wx.getSystemInfo({
success: function(res) {

var language = res.language; // 用户的语言设置，例如zh_CN

}
})

Pass the language value to the server, and the server selects the corresponding language file based on the value and returns it to the applet.

4. Display multi-language text
   In the code of the mini program, we can display the corresponding text content according to the current language setting. For example:

wx.request({
url: 'xxx',
success: function(res) {

// 根据返回的语言文件设置文本内容
var helloText = res.data.hello;
var welcomeText = res.data.welcome;

// 显示文本内容
// ...

}
})

Through the above steps, we have achieved multi-language support for WeChat mini programs. Users of any language can use the language they set to display the text content of the WeChat applet.

3. Summary
This article introduces how to use EasyWeChat and PHP to build multi-language support for WeChat mini programs. By managing and processing text content in different languages, we can make WeChat mini programs more adaptable to the needs of users in different countries and regions. I hope this article will be helpful to you, and I wish you better results in developing WeChat mini programs!

Code example:
Language setting for WeChat applet:

wx.getSystemInfo({
success: function(res) {

var language = res.language; // 用户的语言设置，例如zh_CN

}
})

PHP server interface:

$language = $_GET['language']; // Get language settings

// Return the corresponding language file according to the language setting
if($language == 'zh_CN') {
echo file_get_contents('zh-CN.json');
} elseif($language = = 'en_US') {
echo file_get_contents('en-US.json');
} else {
echo file_get_contents('default.json');
}

?>

In the above code example, we obtain the language setting passed by the applet through $_GET['language'], and then return the corresponding language file based on this value. You can modify and optimize according to actual needs.

I hope the above content can help you, and I wish you success in using EasyWeChat and PHP to build multi-language support for WeChat mini programs!
