php 中文转拼音首字母问题
原始代码有些问题，我做了些更改，原地址github 的 chenall/chenall/blob/master/php/tools/ZH-cn_TO_pinyin.php
<?php/*
中文汉字转拼音首字母的PHP简易实现方法.
要求:?只能是GB2312码表里面中文字符
转换得到字符串对应的拼音首字母大写.
用法:
echo?zh2py::conv('Chinese?中华人民***和国');//Chinese?ZHRMGHG
或
$py?=?new?zh2py;
echo?$py->conv('Chinese?中华人民***和国');//Chinese?ZHRMGHG
*/
class?zh2py
{
//根据汉字区位表
//我们可以看到从16-55区之间是按拼音字母排序的,所以我们只需要判断某个汉字的区位码就可以得知它的拼音首字母.
//区位表第一部份,按拼音字母排序的.
//16区-55区
/*
'A'=>0xB0A1,?'B'=>0xB0C5,?'C'=>0xB2C1,?'D'=>0xB4EE,?'E'=>0xB6EA,?'F'=>0xB7A2,?'G'=>0xB8C1,'H'=>0xB9FE,
