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

/*
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 中华人民共和国');//Chinese ZHRMGHG
或
$py = new zh2py;
echo $py-conv('Chinese 中华人民共和国');//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
/*

php 将中文转换为GBK编码
1、运行控制台，程序-运行，输入CMD，点击确定进入DOS操作系统 快捷键windows键+R键。
2、编写需要运行的java代码。
3、切换运行目录到您存放java代码的目录！使用命令 cd 切换。
4、解决错误提示：编码 GBK 的不可映射字符，使用命令：javac -encoding utf-8 helloword.java，编译成功。
5、成功编译后，在tmp目录下能看到helloword.java文件编译后的.class字节码文件。使用命令【 java helloword 】，运行java程序。
php怎样把utf8转换为gbk
?php@header("Content-type:text/html;charset=UTF-8");echo $str= '你好,这里是卖咖啡!';echo 'br /';echo iconv("UTF-8","gbk//TRANSLIT",$str);; //将字符串的编码从UTF-8转到GB2312
echo 'br /';echo iconv_substr($str, 1, 1, 'UTF-8'); //按字符个数截取而非字节print_r(iconv_get_encoding()); //得到当前页面编码信息echo iconv_strlen($str, 'UTF-8'); //得到设定编码的字符串长度?
gbk转换为utf8的方法：
?php
@header("Content-type:text/html;charset=GB2312");echo $str= '你好,这里是卖咖啡!';echo 'br /';echo iconv('GB2312', 'UTF-8', $str); //将字符串的编码从GB2312转到UTF-8echo 'br /';echo iconv_substr($str, 1, 1, 'GB2312'); //按字符个数截取而非字节print_r(iconv_get_encoding()); //得到当前页面编码信息echo iconv_strlen($str, 'GB2312'); //得到设定编码的字符串长度?
