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

We can use a Chinese character encoding to determine the first Chinese character in Chinese characters. The following is an example, which is very simple and easy to use.

The following is an example, which is very simple and easy to use.

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:

 = 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 $asc <= - 20284) return "A";    if ($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.

  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

In addition, in the getfirstchar function, we have two writing methods:

The first is the example we used above.

 = Ord ("A") and $ fchar <= ord ("z") return strtoupper ($ s0 {0});?> // The other method is the numeric method we use, which is also relatively simple.
 = 65 & $ firstCharOrd <= 91) | ($ firstCharOrd> = 48 & $ firstCharOrd <= 57) return strtoupper ($ string {0});}?>
