mysql_set_charset('utf-8',$con);
mysql_select_db("dbl",$con);

$time=date('Y-m-d h:i:s',time());
//获取条数

$num_rows=mysql_num_rows($rs);//mysql_num_rows返回查询记录条数
if (isset($_POST["submits"])) {
if(!$_POST["message"]==null){
$queryinsert=sprintf("insert into message (message,time) values('%s','%s')",
$_POST['message'],$time);
