//拼音转化函数
function PinYin($str){

for($i=0;$i<strlen($str);$i++){

//转化函数

return chr($num);
}elseif($num”-10247″){

}else{ //汉字，查找对应拼音
for($i=count($this->_code)-1;$i>=0;$i–){
if($this->_code[$i][1]<=$num)

}
return substr($this->_code[$i][0],0,1);
}
}
}
下面这个是用来测试代码的:
复制代码 代码如下:
<?php
include_once ‘charset.class.php’;
header(‘Content-type: text/html;charset=utf-8’);
$charset=new charset();
foreach(array(‘武汉’,’中国’,’上海’) as $val){
echo iconv(‘gbk’,’utf-8//IGNORE’,strtoupper($charset->PinYin(mb_convert_encoding($val,’gbk’,’utf-8′))));
echo ‘
‘;
}
三、这是网上找到个一个方法,经过测试可以正常使用,但对一些生僻字或者特殊字符会有问题.
复制代码 代码如下:
function getFirstCharter($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==$str?$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;
}
