保持最大长度,且文字完整
只支持GBK,UTF8的先转GBK再执行

function gbk_left($str,$len){<br>         if(strlen($str)         $txt='';<br>         for($i=0;$i             if(ord($str{$i})>0x80){<br>                 if($i+1==$len) return $txt;<br>                 $txt.=$str{$i}.$str{$i+1};<br>                 $i++;<br>                 continue;<br>             }<br>             $txt.=$str{$i};<br>         }<br>         return $txt;<br>     }
