设置字符集后怎么还乱码
$load_list 是一个二维数组，将其中的user_name值取出前两个字符，后面用星号代替，但是设置字符集后还是有乱码，但是中文是要显示前两个字符，后面用星号表示
foreach($load_list as $k=>&$v){
$temp=&$v['user_name'];
//判断是否有中文
if (!preg_match('/^([\x81-\xfe][\x40-\xfe]){0,2}$/',$temp)){
$len=mb_strlen($temp,'utf-8');
}else{
$len=strlen($temp);
}
for($k=0;$k<$len;$k++){
if($k>1){
$temp[$k]='*';
}
