PHP 汉字转拼音源码（GB2312类库，大约支持6000个汉字左右）

    最近一个项目中使用php作为为前端提供数据的开发语言，为了实现能够按照字母排序，需要提取中文的汉语拼音，借这个项目写了个汉字转拼音的脚本，脚本比较简单，注释也比较详细，这里就不多说了，直接上代码了。

$py = new PinYin();
           $all_py = $py->get_all_py("吴国伟"); //输出 ['wu','guo','wei']，输出字符串调用join方法,join('',$all_py)
           $first_py = $py->get_first_py($all_py);//输出 wgw
           $first_letter = $py->get_first_letter($all_py);// 输出 w
