一、公司同事整理的类,挺实用的.相信拿出来分享下他不会介意的O(∩_∩)O.不过如果首字母是数字或英文会有些问题.

}
下面这个是用来测试代码的:
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($val,'gbk','utf-8'))));
echo '
';
}
三、这是网上找到个一个方法,经过测试可以正常使用,但对一些生僻字或者特殊字符会有问题.
function getFirstCharter($str){
if(empty($str)){return '';}
$fchar=ord($str{0});
if($fchar>=ord('A')&&$fchar $s1=iconv('UTF-8','gb2312',$str);
$s2=iconv('gb2312','UTF-8',$s1);
