[PHP] Cookie header and location header.
In PHP4.3.x If I set a cookie with setcookie and send a location header immediately. I find no problem for the task. That is, And testcookie can be found in the latter page. However, I can't In PHP4.1.x What's the problem?

Re: [PHP] Cookie, header, output problems
You should not add any output after doing a "Location:" redirect. It's
recommended to add an exit() after the header(). Proper browsers should
halt their renderer and redirect when they find a Location: header.

freaking out when there isn't any output after a cookie is set and a
header is sent.
I'm also having another similar problem with this function:
function auth($redirect_url) {
global $HTTP_COOKIE_VARS;
if (!isset($HTTP_COOKIE_VARS['jackloren_user'])) {
header("Location: http://www.jackloren.com/login.php";);
// echo "test";
} else {
$userinfo = explode(":",
$HTTP_COOKIE_VARS['jackloren_user']);
$username = $userinfo[0];
$userpass = $userinfo[1];
echo "$username | $userpass";
if (mysql_num_rows(mysql_query("select * from
`$cart->user_table` where username=\"$username\" and
userpass=\"$userpass\"", $cart->dblink)) != 1) {
redirectURL("login.php", $redirect_url);
} else {
echo "success";
// nothing
}
}
}
If I leave the script the way it is, the browser isn't redirected no
matter what I put in the header() statement. However, if I uncomment
the echo statement, giving the browser some output, then the redirect
works fine.
Has anyone experienced this? And if so, how do I fix it? Thanks.

It is not. However, a MySQL error is indeed output. Make
sure your query is successful.
My suggestion would be to simplify your code. Test your
queries independently of setting cookies and redirecting.
You have too many potential cases for error as it is, and
that makes things difficult.

I'm not sure if it is just formatting or my eyes, but it
looks like you have backticks in your query. Also, you
should consider using single quotes around your values
rather than escaped double quotes.
> setcookie("jackloren_user", "$username:$userpass", time()
> + 2592000);
> header("Location: http://www.jackloren.com/";);
You should test this combination separately. Depending on
several factors, your cookie may not be getting set due to
the Location header redirect. The combination works fine
with most modern Web agents, but it has been known to pose
problems for developers.
