A function that converts Chinese characters into pinyin.

Many problems are caused by Chinese characters. if the file name is better to use Chinese characters, the current solution is to generate an ID, this ID is used as a file name. if the url contains Chinese characters, the current solution often uses urlencode encoding and now uses this conversion, which is much better. principle: using multi-dimensional array 1. add index 2. traverse the array? $ Darray (arra

Many problems are caused by Chinese characters.
For example, it is best not to use Chinese characters for file names.
The solution is to generate an ID, which is used as the file name.
If the url contains Chinese characters on the webpage, errors often occur.
The current solution generally uses urlencode encoding.

It's much better to use this conversion.

Principle: multidimensional array
1. add an index
2. traverse the array
