How to implement an API interface in PHP that can convert Chinese characters into Pinyin?

In many Chinese applications, it is often necessary to convert Chinese characters into Pinyin to implement some functions, such as search, sorting, etc. This article will introduce how to implement an API interface in PHP that can convert Chinese characters into Pinyin.

Before implementing this function, we first need a PHP pinyin conversion library. Now, there are many open source PHP pinyin conversion libraries to choose from, such as pinyin, overtrue-pinyin, etc. These libraries all provide the function of converting Chinese characters into Pinyin, and are very convenient to use. In this article, we will use pinyin to achieve this.

1. Install the pinyin library

To use the pinyin library, we first need to install it through Composer. Execute the following command in the terminal to install the pinyin library:

composer require overtrue/pinyin

2. Implement the conversion interface

Next, we need to implement a conversion interface in the PHP file to receive Chinese characters and convert Convert it to pinyin. Create a file named pinyin.php and enter the following code:

// 引入pinyin库
require './vendor/autoload.php';

// 设置编码
header('Content-Type: application/json; charset=utf-8');

// 获取传入的中文字符
$chinese = $_GET['chinese'] ?? '';

// 将中文字符转换为拼音
$pinyin = OvertruePinyinPinyin::trans($chinese, OvertruePinyinMemoryFileDictLoader::class);

// 返回JSON格式的结果
echo json_encode(['pinyin' => $pinyin], JSON_UNESCAPED_UNICODE);

In the above code, we first introduced the pinyin library, and then set the output encoding to utf-8. Next, the incoming Chinese characters are obtained through $_GET['chinese']. Use the OvertruePinyinPinyin::trans method to convert Chinese characters to Pinyin and store them in the $pinyin variable. Finally, we return the converted pinyin in JSON format.

3. Test

Now, we can test our API interface in the browser. Suppose we place the pinyin.php file in the root directory of the local server. Enter the following URL in the address bar of the browser:

http://localhost/pinyin.php?chinese=你好

Click Enter, we will get the following result:

{"pinyin":"nǐhǎo"}

This is the result of converting the Chinese character "Hello" into Pinyin. We can modify the code according to our needs to achieve more functions, such as converting pinyin to initial letters, setting the conversion format, and so on.

Summary

By using the pinyin library, we can easily implement an API interface for converting Chinese characters into Pinyin in PHP. In addition, we can also expand the interface according to actual needs to meet different business needs. This API interface can be used in many Chinese applications to provide users with a better user experience.
