现实中我们经常看到这样的说明,排名不分先后,按姓名首字母进行排序。这是中国人大多数使用的排序方法。

那么在php程序中该如何操作呢?

下面就分享一下在php程序中获取汉字拼音的首字母的方法,在网上搜到的大多数是有问题的,这个可是经过作者实践应用过的,真的可以使用的哦。

<p>//php获取中文字符拼音首字母</p>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;<br /><p>}</p>
