下面这个是用来测试代码的:
<?php</P><P>include_once 'charset.class.php';<BR>header('Content-type: text/html;charset=utf-8');</P><P>$charset=new charset();<BR>foreach(array('武汉','中国','上海') as $val){<BR> echo iconv('gbk','utf-8//IGNORE',strtoupper($charset->PinYin(mb_convert_encoding($val,'gbk','utf-8'))));<BR> echo '<br />';<BR>}
三、这是网上找到个一个方法,经过测试可以正常使用,但对一些生僻字或者特殊字符会有问题.
function getFirstCharter($str){<BR> if(empty($str)){return '';}<BR> $fchar=ord($str{0});<BR> if($fchar>=ord('A')&&$fchar<=ord('z')) return strtoupper($str{0});<BR> $s1=iconv('UTF-8','gb2312',$str);<BR> $s2=iconv('gb2312','UTF-8',$s1);<BR> $s=$s2==$str?$s1:$str;<BR> $asc=ord($s{0})*256+ord($s{1})-65536;<BR> if($asc>=-20319&&$asc<=-20284) return 'A';<BR> if($asc>=-20283&&$asc<=-19776) return 'B';<BR> if($asc>=-19775&&$asc<=-19219) return 'C';<BR> if($asc>=-19218&&$asc<=-18711) return 'D';<BR> if($asc>=-18710&&$asc<=-18527) return 'E';<BR> if($asc>=-18526&&$asc<=-18240) return 'F';<BR> if($asc>=-18239&&$asc<=-17923) return 'G';<BR> if($asc>=-17922&&$asc<=-17418) return 'H';<BR> if($asc>=-17417&&$asc<=-16475) return 'J';<BR> if($asc>=-16474&&$asc<=-16213) return 'K';<BR> if($asc>=-16212&&$asc<=-15641) return 'L';<BR> if($asc>=-15640&&$asc<=-15166) return 'M';<BR> if($asc>=-15165&&$asc<=-14923) return 'N';<BR> if($asc>=-14922&&$asc<=-14915) return 'O';<BR> if($asc>=-14914&&$asc<=-14631) return 'P';<BR> if($asc>=-14630&&$asc<=-14150) return 'Q';<BR> if($asc>=-14149&&$asc<=-14091) return 'R';<BR> if($asc>=-14090&&$asc<=-13319) return 'S';<BR> if($asc>=-13318&&$asc<=-12839) return 'T';<BR> if($asc>=-12838&&$asc<=-12557) return 'W';<BR> if($asc>=-12556&&$asc<=-11848) return 'X';<BR> if($asc>=-11847&&$asc<=-11056) return 'Y';<BR> if($asc>=-11055&&$asc<=-10247) return 'Z';<BR> return null;</P><P>}
