獲取給出漢字中拼音的第一個漢字字母我們可以利用漢字的一個編碼來進行判斷,下面我們來給大家介紹一個例子,非常的簡單好用.

先來看看怎樣取得單個漢字的拼音首字母,請看下面這個函數,它支持GBK和UTF8編碼,代碼如下:

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 "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;

}

以上函數返回單個漢字的拼音首字母,當需要處理中文字符串時,只需要重新寫一個函數,用來取得一串漢字的拼音首字母,代碼如下:

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 > 160){

   $s2 = substr($zh,$i++,2);

   $ret .= getfirstchar($s2);

  }else{//開源軟件:Vevb.com

   $ret .= $s1;

  }

}

return $ret;

}

上面這個函數就是獲取漢字拼音首字母的函數,使用示例:

echo pinyin1('這是中文字符串');

結果輸出:ZSZWZFC

補充在 getfirstchar函數中我們有兩種寫法

第一種是我們上面用到的例子,代碼如下:

function getfirstchar($s0){

$fchar = ord($s0{0});

if($fchar >= ord("A") and $fchar <= ord("z") )return strtoupper($s0{0});

而另一種是我們使用的數字方法了,也比較簡單了,代碼如下:

function getFirstChar($string) {

$firstCharOrd = ord(strtoupper($string{0}));

if (($firstCharOrd >= 65 && $firstCharOrd <= 91) || ($firstCharOrd >= 48 && $firstCharOrd <= 57))

return strtoupper($string{0});
