What header problems do you have? Starting with a call to session_start(),
followed by a header() call shouldn't cause any problems.
Even several header() calls do not cause errors, because headers are send
only when content is displayed or at the end of the script (whatever comes
first):
<?php
// header not send
header("X-Header: Foo");
header("X-Header-Description: Bar");
// headers are send
print "Hello";
// Error because the headers are already sent
header("Location: http://example.com/");
?>
Or:
<?php
// header not send
header("X-Header: Foo");
header("X-Header-Description: Bar");
header("Location: http://example.com/");
// No more lines of code, headers will be send
?>
Even the above examples would work when you instruct PHP to wait sending the
output through output buffering (see http://www.php.net/ob_start).

Hi.
I receive the following error:
Warning: Cannot modify header information - headers already sent by
(output started at /home/xxxxx/public_html/newland/login.php:11) in
/home/xxxxx/public_html/newland/login.php on line 55
This is line 55 to 61 below:
header("Location: ". $MM_redirectLoginSuccess );
}
else {
header("Location: ". $MM_redirectLoginFailed );
}
}
?>
Do I just move that to the top then after the session start?
