Pinyin library creation php

Mainly implements obtaining Chinese names from a database and obtaining all possible pinyin uppercase letter combinations. Then import it into another database together with the name

Because the names involved are Chinese characters, the editing environment used is UTF-8. Among them, the permutation and combination function was borrowed from others, and I thought about it for a long time, but the result was not good. The key is that the logical thinking of data is not clear, which shows the importance of data thinking.

I am also learning by doing, and I am not very proficient in calling PHP functions. I will need to practice more programming in the future. If there is anything poorly written, you are welcome to correct me, communicate with each other, and make progress together!
