How to get the first letter of Chinese pinyin in php, how to get the first letter of Chinese pinyin in php

In reality, we often see such instructions, in no particular order, sorted by the first letter of the name. This is the sorting method used by most Chinese people. So how to operate it in php program?

Now I will share how to get the first letter of Chinese Pinyin in the PHP program. Most of the methods found on the Internet are problematic, but this has been applied by the editor in practice and it can really be used.

//php获取中文字符拼音首字母 
function getFirstCharter($str){ 
 if(empty($str)){return '';} 
 $fchar=ord($str{0}); 
 if($fchar>=ord('A')&&$fchar<=ord('z')) return strtoupper($str{0}); 
 $s1=iconv('UTF-8','gb2312',$str); 
 $s2=iconv('gb2312','UTF-8',$s1); 
 $s=$s2==$str&#63;$s1:$str; 
 $asc=ord($s{0})*256+ord($s{1})-65536; 
 if($asc>=-20319&&$asc<=-20284) return 'A'; 
 if($asc>=-20283&&$asc<=-19776) return 'B'; 
 if($asc>=-19775&&$asc<=-19219) return 'C'; 
 if($asc>=-19218&&$asc<=-18711) return 'D'; 
 if($asc>=-18710&&$asc<=-18527) return 'E'; 
 if($asc>=-18526&&$asc<=-18240) return 'F'; 
 if($asc>=-18239&&$asc<=-17923) return 'G'; 
 if($asc>=-17922&&$asc<=-17418) return 'H'; 
 if($asc>=-17417&&$asc<=-16475) return 'J'; 
 if($asc>=-16474&&$asc<=-16213) return 'K'; 
 if($asc>=-16212&&$asc<=-15641) return 'L'; 
 if($asc>=-15640&&$asc<=-15166) return 'M'; 
 if($asc>=-15165&&$asc<=-14923) return 'N'; 
 if($asc>=-14922&&$asc<=-14915) return 'O'; 
 if($asc>=-14914&&$asc<=-14631) return 'P'; 
 if($asc>=-14630&&$asc<=-14150) return 'Q'; 
 if($asc>=-14149&&$asc<=-14091) return 'R'; 
 if($asc>=-14090&&$asc<=-13319) return 'S'; 
 if($asc>=-13318&&$asc<=-12839) return 'T'; 
 if($asc>=-12838&&$asc<=-12557) return 'W'; 
 if($asc>=-12556&&$asc<=-11848) return 'X'; 
 if($asc>=-11847&&$asc<=-11056) return 'Y'; 
 if($asc>=-11055&&$asc<=-10247) return 'Z'; 
 return null; 
} 

For example:

echo getFirstCharter('帮客之家www.jb51.net');//结果将输出：J 

The above is the function of PHP to obtain the first letter of Chinese pinyin. I hope it can help everyone learn PHP programming better.
