例如：$str = ‘中华人民’;

返回来 ZHRM；

下面是我百度的一个函数，但是有的情况会出错，例如： 重庆

返回来的是 ZQ

<code>function getfirstchar($s0) {        $firstchar_ord = ord(strtoupper($s0{0}));        if (($firstchar_ord >= 65 and $firstchar_ord = 48 and $firstchar_ord = -20319 and $asc = -20283 and $asc = -19775 and $asc = -19218 and $asc = -18710 and $asc = -18526 and $asc = -18239 and $asc = -17922 and $asc = -17417 and $asc = -16474 and $asc = -16212 and $asc = -15640 and $asc = -15165 and $asc = -14922 and $asc = -14914 and $asc = -14630 and $asc = -14149 and $asc = -14090 and $asc = -13318 and $asc = -12838 and $asc = -12556 and $asc = -11847 and $asc = -11055 and $asc <= -10247)            return "Z";        return null;    }</code>

可以尝试使用这个拼音库:

可以使用 http://overtrue.me/pinyin/，开源项目

多音字没办法解决，除非你自己写枚举排除
