How to get the first letter of pinyin in a string in php

For example: $str = 'People of China';

Come back to ZHRM;

The following is a function of my Baidu, but it may go wrong in some cases, for example: Chongqing

The one who returned is 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 </code>

You can try this Pinyin library:

http://overtrue.me/pinyin/
http://overtrue.me/articles/2014/10/php-chinese-to-pinyin.html

You can use http://overtrue.me/pinyin/, an open source project

There is no way to solve polyphonic characters, unless you write an enumeration to exclude them yourself
