Optimizes the traditional Pinyin conversion processing algorithm, specifically processing the UTF-8 character set.
If you use the GBK or GB2312 character set, you only need to remove the iconv function and assign the value directly without conversion.

Not much to say, just upload the code, it is completely open source and you can use it directly. If you find it useful, please help retain the author's information when using it.

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above has introduced PHP's UTF-8 Chinese to Pinyin processing class, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
