[code]

实例化
$comment=""//你要输出的文件
if (isset($_GET['f_page']))
{
$f_page= intval($_GET['f_page']);
}
else
{
$f_page=1;
}
$PageWordNum=200;
$str_page=new strPage();
$scomment= $str_page->SubstrGB($comment,($f_page-1)*$PageWordNum,$PageWordNum);
//echo $scomment;
echo (iconv("gb2312","UTF-8",$scomment));
$spage=$str_page->ff_page($f_page,$url_str);
echo $spage;


[/code]

打开extension=php_mbstring.dll

恕小的不敬，折腾半天就截取不乱码的事
我还以为版主把智能断页，解析html的问题解决了
