// 文件说明：Discuz论坛帖子首页调用（菜鸟简洁版）
// --------------------------------------------------------------//
// 程序作者：Spring
// --------------------------------------------------------------//
// 程序主页：http://www.mephp.com
// --------------------------------------------------------------//
// 使用方法：把discuz_js.php放在论坛根目录；再在调用页添加以下JS
// <script src="discuz/discuz_js.php?new=8&post=3&hot=6"></script>
// new=8&post=3&hot=6可以选择你所需要的参数，也可以不要，既可以这样
// new=8或者post=3或者hot=6或者new=8&post=3或者post=3&hot=6
include "config.php";
//==========================变量定义===============================
$titlelength  = 20; //标题长度，按字节
$discuz_table = $tablepre."threads"; //discuz表名
$new       = $HTTP_GET_VARS['new']; //最新发表显示标题数
$post       = $HTTP_GET_VARS['post'];//最新回复显示标题数
$hot       = $HTTP_GET_VARS['hot']; //回复最多显示标题数
//===========================字符截取函数（防乱码）=================
function m_substr($str,$start=0,$strlen) {
for($i=0;$i<$strlen;$i++)
   if(ord(substr($str,$i,1))>0xa0) $j++;
if($j%2!=0) $strlen++;
$str=substr($str,0,$strlen);
return $str;
}
//===========================调用Discuz帖===========================
