//建立数据库链接
$conn = @mysql_connect("localhost", "root", "123123") or die("数据库链接错误");
//指定要链接的数据库
mysql_select_db("tipask", $conn);
//使用UTF-8中文编码;
mysql_query("set names 'UTF-8'");
//指定版块的所有文章中取10条最新帖子
$SQL=="select id,title FROM ask_question order by id desc limit 9";
$query=mysql_query($SQL);
//循环显示结果
while($row=mysql_fetch_array($query)){
