php中输出中文字符乱码
问题如下:
$load_list 是一个二维数组,将其中的user_name值取出前两个字符,后面用星号代替,但是遇到中文字符就出现乱码,设置header()函数,也没用,求解决办法,谢谢!
foreach($load_list as $k=>&$v){
 $temp=&$v['user_name'];

 for($i=0,$len=strlen($temp);$i if($i>1){
  $temp[$i]='*';
}
 }
}

截图如下:
------解决方案--------------------
你的代码只适用于单字节字符串,没有考虑到
中文 gbk 一个字符 2 个字节
中文 utf-8 一个字符 3 个字节
------解决方案--------------------
试试mb_substr函数
