[PHP] PhP 4.2.1 (and various)
Hi! I've recently upgraded to 4.2.1, but i have gotten a lot of problems with it. First of all my pbpBB 2.0 forums stopped working (http://utge.dyndns.org/phpbb2/index.php). When you try to log in i get an error, malfomed header request? (im not on the actual machine now :)). I also have problems with logins to my site (jaggu.org). After messing a lot to get sessions working again, I have tracked down the consisten problem to the Header () function. A comment in the manual says should be put in front of all function calls before header(). I tried that, to no use. So my question is, why has that changed, and what do we do now to authenticate users and redirect them to anothe page? And what the hell is this thingy, i cant see to find anything on it in the manual, and search doesnt work for chars like that. I hope you guys can clarify this for me.

Do they use variables straight up, rather than via the new superglobals such as
$_POST? Simple solution, change your php.ini to have register_globals = on.
(http://utge.dyndns.org/phpbb2/index.php). When you
try to log in i get an error, malfomed header request?
I guess somewhere, some text is being sent out to the browser before the header()
functions are being called. Perhaps due to a different level of error reporting in
your new php.ini setup?
So my question is, why has that changed, and what do
we do now to authenticate users and redirect them to
anothe page? And what the hell is this thingy, i
cant see to find anything on it in the manual, and

The represses error messages. For example:
mail('', 'subject', 'body');
will produce an error message, that the to address is bad, while
mail('', 'subject', 'body');
will silently fail.
Rather than doing that, it's better to write your code so that there won't be error
messages in the first place.

Not only that: if you are running a production server, you will probably
want to log your error messages to a file (or syslog, or whatever),
instead of printing them. So 'display_errors' should be off. If that is
the case, you don't need to use anymore, because there will be no HTML
output even in case of problems. The advantage of this is that you can
use the exact same code on a development server (with display_errors =
on) and a production server.

That is all well, but if php 4.2.1 interprets any
output (as errors not only screen errors) as something
that is sent before a header in a redirect, there is
no other way (that i'm aware of) around it.
Like this:
$user=$Session[user];
if(!$Authorized)
{
header (Location: http://jaggu.org;);
}
this will not work, you have to write:
@$user=@$Session[user];
@if(@!$Authorized)
{
header (Location: http://jaggu.org;);
}
To actually get the redirect.
On http://jaggu.org/info.php, you can see that
display_errors = off
In any case, I think you are onto something. I will
try to narrow down logging, to see if that might be
the problem.
Thanks for helping!

As I was saying before, write your code in a way that doesn't generate error
messages. For example, the above passage would be error free if you did this...
if( empty($Authorized) ) {
header ('Location: http://jaggu.org');
} else {
$user = $Session['user'];
}

That's not new to 4.2.1.
The solution remains the same as always: Choose between either:
A) Using output buffering; or
B) Make sure you don't generate any output before sending headers. You
don't need to stick in front of everything, just eliminate all errors
from your code and then make sure you aren't printing stuff.
For better or worse, there's no scapegoat here.

Thanks for the reply, but it didnt help :)
The code is without errors. What I submitted was
written on the fly to illustrate what i tried to do.
Here is the actual code...
$playername=$_GET['player'];
if (!$playername)
{
..print HTML form code...
}
else
{
if ($playername)
{
$_SESSION['playername']=$playername;
header('Location:
http://'.$_SERVER['HTTP_HOST'].'/UTGE/index.html');
}
else
{
die (something gone wrong! Do it properly);
}
}
I also tried with ~all in logging and without logging
at all.

Perhaps because you're ignoring what I said.

This will generate an error message if there's no player variable in the

for empty($_GET['player'])

{
..print HTML form code...
}
else

Why are you testing for playername again? You already know it's there
because your'e in the else after the if (!$playername) statement.
