<?php/*
中文漢字轉拼音首字母的PHP簡易實現方法.
要求:?只能是GB2312碼表裏面中文字符
轉換得到字符串對應的拼音首字母大寫.
用法:
echo?zh2py::conv('Chinese?中華人民***和國');//Chinese?ZHRMGHG
或
$py?=?new?zh2py;
echo?$py->conv('Chinese?中華人民***和國');//Chinese?ZHRMGHG
*/
class?zh2py
{
//根據漢字區位表
//我們可以看到從16-55區之間是按拼音字母排序的,所以我們只需要判斷某個漢字的區位碼就可以得知它的拼音首字母.
//區位表第壹部份,按拼音字母排序的.
//16區-55區
