It seems to be a BOM problem

The error is: Cannot modify header information - headers already sent by ……
I’m sure there is no output before the header
Use editplus to also remove bom
phpini is also set to on
Ob_start
was also added before Nothing works [img]http://www.111cn.cn/bbs/images/smilies/default/mad.gif[/img]
Is there any other way?

Please comment out this sentence and take a look. It is probably because the BOM in db.php has not been removed. There is no problem with your code here.

session_start();

require_once('db.php');

//print_r($_POST);



$num=mysql_query("select user,pass from user");

while ($run=mysql_fetch_assoc($num)) {

if ($_POST['name']===$run['user']&&md5($_POST['name2'])===$run['pass']) {

$_SESSION['userid']=$_POST['username'];

header("location: lo.php");

die();

}else {

header("location: msg.php");

}

}

ob_end_flush();

?>
