//连接到数据库
$conn = @mysql_connect("localhost","root","root") or die("数据库连接失败,请检查你的网络,稍后再试试");
//选定数据库
mysql_select_db("test");
//执行SQL语句(查询)
mysql_query("set names 'utf8'");
$sql = "INSERT INTO `test`.`message` (`id`,`user`, `title`, `content`, `lastdate`) VALUES (NULL, '$user', '$title', '$content', now())";
mysql_query($sql);
//关闭数库
mysql_close($conn);
