请问这个获得新闻标题的语句：$title=substr($row[title],"0",$titlelen")."..."为什么在显示的时候在最后面老是加问号怎么解决？

Question

出现了半个汉字
$title=substr($row[title],"0",$titlelen").chr(0)."..."

Answer 1

function  csubstr($string,$start,$length)        
       {  
               $str="";  
               $len=$start+$length;  
               for($i=$start;$i<$len;$i++){  
                       if(ord(substr($string,$i,1))>0xa0){        
                               $str.=substr($string,$i,2);        
                               $i++;        
                       }        
                       else          
                               $str.=substr($string,$i,1);  
               }                    
                         
               return  $str;                
       }

Answer 2

function ccStrLeft($str,$len) #从左边截取中英文混合字符串
{
    $ascLen=strlen($str);   if($ascLen<=$len) return $str;
    $hasCC=ereg("[\xA1-\xFE]",$str); #同上
    $hasAsc=ereg("[\x01-\xA0]",$str);
    if(!$hasCC) return substr($str,0,$len);
    if(!$hasAsc)
     if($len & 0x01) #如果长度是奇数
        return substr($str,0,$len+$len-2);
     else
         return substr($str,0,$len+$len);
    $cind=0;$flag=0;
    while($cind<$ascLen)
    {
        if(ord(substr($str,$cind,1))<0xA1) $flag++;
        $cind++;
    }
     if($flag & 0x01)
        return substr($str,0,$len);
     else
         return substr($str,0,$len-1);
