Example of getting the first letter of Chinese characters and pinyin in PHP

Let's take a look at how to get the first letter of a single Chinese character. See the following function. It supports GBK and UTF8 encoding:

The code is as follows:

Copy code

Function getfirstchar ($ s0 ){ $ Fchar = ord ($ s0 {0 }); If ($ fchar> = ord ("A") and $ fchar <= ord ("z") return strtoupper ($ s0 {0 }); $ S1 = iconv ("UTF-8", "gb2312", $ s0 ); $ S2 = iconv ("gb2312", "UTF-8", $ s1 ); If ($ s2 = $ s0) {$ s = $ s1;} else {$ s = $ s0 ;} $ Asc = ord ($ s {0}) * 256 + ord ($ s {1})-65536; If ($ asc >=- 20319 and $ asc <=-20284) return ""; If ($ asc >=- 20283 and $ asc <=-19776) return "B "; If ($ asc >=- 19775 and $ asc <=-19219) return "C "; If ($ asc >=- 19218 and $ asc <=-18711) return "D "; If ($ asc >=- 18710 and $ asc <=-18527) return "E "; If ($ asc >=- 18526 and $ asc <=-18240) return "F "; If ($ asc >=- 18239 and $ asc <=-17923) return "G "; If ($ asc >=- 17922 and $ asc <=-17418) return "H "; If ($ asc >=- 17417 and $ asc <=-16475) return "J "; If ($ asc >=- 16474 and $ asc <=-16213) return "K "; If ($ asc >=- 16212 and $ asc <=-15641) return "L "; If ($ asc >=- 15640 and $ asc <=-15166) return "M "; If ($ asc >=- 15165 and $ asc <=-14923) return "N "; If ($ asc >=- 14922 and $ asc <=-14915) return "O "; If ($ asc >=- 14914 and $ asc <=- 14631) return "P "; If ($ asc >=- 14630 and $ asc <=-14150) return "Q "; If ($ asc >=- 14149 and $ asc <=-14091) return "R "; If ($ asc >=- 14090 and $ asc <=-13319) return "S "; If ($ asc >=- 13318 and $ asc <=-12839) return "T "; If ($ asc >=- 12838 and $ asc <=-12557) return "W "; If ($ asc >=- 12556 and $ asc <=-11848) return "X "; If ($ asc >=- 11847 and $ asc <=-11056) return "Y "; If ($ asc >=- 11055 and $ asc <=- 10247) return "Z "; Return null; }

The above function returns the first letter of a single Chinese character.

To process a Chinese string, you only need to write a new function to obtain the first letter of a string of Chinese characters.

The code is as follows:

Copy code

Function pinyin1 ($ zh ){ $ Ret = ""; $ S1 = iconv ("UTF-8", "gb2312", $ zh ); $ S2 = iconv ("gb2312", "UTF-8", $ s1 ); If ($ s2 = $ zh) {$ zh = $ s1 ;} For ($ I = 0; $ I <strlen ($ zh); $ I ++ ){ $ S1 = substr ($ zh, $ I, 1 ); $ P = ord ($ s1 ); If ($ p & gt; 160 ){ $ S2 = substr ($ zh, $ I ++, 2 ); $ Ret. = getfirstchar ($ s2 ); } Else { $ Ret. = $ s1;   }  } Return $ ret; } The above function is used to obtain the first letter of Chinese characters and pinyin. Example: Echo pinyin1 ('This is a Chinese string ');

Result output: ZSZWZFC

Supplement inThe getfirstchar function can be written in two ways.

The first is the example we used above.

The code is as follows:	Copy code
Function getfirstchar ($ s0 ){ $ Fchar = ord ($ s0 {0 }); If ($ fchar> = ord ("A") and $ fchar <= ord ("z") return strtoupper ($ s0 {0 });

The other is the numeric method we use, which is also relatively simple.

The code is as follows:	Copy code
Function getFirstChar ($ string ){ $ FirstCharOrd = ord (strtoupper ($ string {0 })); If ($ firstCharOrd >=65 & $ firstCharOrd <= 91) | ($ firstCharOrd >=48 & $ firstCharOrd <= 57 )) Return strtoupper ($ string {0 });
