求解：数据插入不到数据库中。
数据库确定已经连接成功了。表名keai_user 字段f_logintimes（登录次数） f_lasttime（最近登录时间） f_loginip（登录IP地址）
$ip = $_SERVER['REMOTE_ADDR'];
$sql = "UPDATE keai_user SET f_logintimes = f_logintimes + 1,";
$sql .= "f_lasttime = now(),f_loginip = '$ip'";
$sql = "WHERE f_username = '$username'";
$db->query($sql);执行后表keai_user 内容没有任何变化，不知道为什么？

------解决方案--------------------

引用$db->query($sql);执行后表keai_user 内容没有任何变化，不知道为什么？

------解决方案--------------------
$sql = "WHERE f_username = '$username'"; 
 
写错了吧！
$sql .= "WHERE f_username = '$username'";
