PHP Chinese character to Pinyin source code (GB2312 class library, supports about 6000 Chinese characters)

In a recent project, PHP was used as the development language to provide data for the front end. In order to be able to sort by letters, it was necessary to extract the Chinese Pinyin. I used this project to write a script to convert Chinese characters to Pinyin. The script is relatively simple and the comments are relatively simple. I won’t go into details here, let’s go directly to the code.

Usage:

$py = new PinYin();
 $all_py = $py->get_all_py("武国伟"); //Output ['wu','guo' ,'wei'], output the string and call the join method, join('',$all_py)
 $first_py = $py->get_first_py($all_py);//Output wgw
 $first_letter = $py->get_first_letter ($all_py);//Output w
