How to convert Chinese characters to Pinyin initials in PHP?

In the process of developing PHP programs, we often encounter the need to convert Chinese characters into the first letters of Pinyin. This requirement is used in some search functions, filtering functions, and data organization. In this article, we will introduce an easy way to achieve this functionality.

First of all, we need to use the Pinyin extension library to assist us in completing the Chinese Pinyin conversion function. You can install the Pinyin extension library through the following code example:

composer require overtrue/pinyin

After the installation is complete, we can use the following code to convert Chinese into Pinyin initials:

use OvertruePinyinPinyin;

$pinyin = new Pinyin();

$chinese = "中文字符";

$initial = $pinyin->abbr($chinese);

echo $initial;

In the above code, we first The Pinyin class is introduced using the use statement, and then the class is instantiated and assigned to the $pinyin variable. Next, we define a $chinese variable and assign it the value "Chinese Character", which is the Chinese character we want to convert.

Finally, we called the abbr method in the $pinyin variable and passed in the $chinese variable as a parameter. The abbr method will return the first letter of the pinyin of the Chinese string.

Finally, we use the echo statement to print out the converted first letters of Pinyin.

Note that you need to ensure that composer has been installed on your server and that composer has been used to manage dependencies in the project. If composer has not been installed, you can refer to the official documentation to install it. If you have not used composer to manage dependencies in your project, you can execute the following code in the root directory of the project:

composer init

Then follow the prompts, and finally add the following content to the composer.json file:

{
  "require": {
    "overtrue/pinyin": "^4.0"
  }
}

Then execute the following command to download and install the Pinyin extension library:

composer install

The above is how to convert Chinese characters into the first letter of Pinyin in PHP. This function can be easily implemented using the Pinyin extension library, and it can also improve development efficiency. Hope this article is helpful to you!
