PHP汉字转换拼音的类

网络上类似的代码大多只能在gb2312编码下使用，下面这个类同时能在utf-8编码下将汉字转换为拼音，具体的代码和用法如下： 

function Pinyin($_String, $_Code='gb2312')

{

$_DataKey = "aaianangaobabaibanbangbaobeibenbengbibianbiaobiebinbingbobucacaicancangcaocecengcha".

"chaichanchangchaochechenchengchichongchouchuchuaichuanchuangchuichunchuocicongcoucu".
