RE: [PHP] header function odd behavior
-Original Message- From: H Rao [mailto:hydsd...@gmail.com] Sent: 28 June 2011 04:40 I am trying to understand odd(different) behavior of the header function under two different environments. Here is the code which I am trying to execute from two different servers ? header (Set-Cookie: c1=value1;path=/; domain=.domain.com); header (Set-Cookie: c2=value2;path=/; domain=.domain.com); ? When executed from server1(OS X), both cookies are set in browser, but when executed from server2(Linux), only the second cookie is set. server1 and server2 are running different OS and php version as below. I know I could add $replace=false option on the Linux server, but I am trying to understand the different behavior of header() function on these two servers. Any thoughts? Well, according to the manual, you need to be using the FALSE parameter anyway since By default it will replace, but if you pass in FALSE as the second argument you can force multiple headers. So the wrong behaviour is on the (older) OS X server, but I'm as confused as you as to why this should be as there is no indication in the manual or the ChangeLog that the default behaviour has changed at any point.

This part will cause an error since outputting anything will cause the
headers to be sent (unless output buffering is on). Once sent, the
headers cannot be modified.
You should also think about using urlencode on the values being sent in
the redirect URLs, or even using a code to reference each error.

I only meant for the quotes around the filename. I'd tried
header(Content-Disposition: attachment; filename='artist -
title.mp3');
before and it didn't work correctly. I hadn't run into the problem of
double quotes inside singe though, as the filenames I was generating
relied on a variable, and I found it easier to just escape the second
set of nested quotes and include the variable directly.
As far as I'm aware, the header() function shouldn't care whether it
uses single or double quotes, so I would assume it's something else
amiss.

Under normal conditions, you can't.
A request is for a single thing. While it is potentially possible to
embed graphics, css, js into a single html file request, downloading
files is not.
Instead, you issue the html first, but include in the head tag, a
meta redirect tag to the URL just for the download file.

output the html you want to send afterwards first,

*is* executed. I've output the value of $numprojects, so I know that it's
greater than 0, so the command
header(Location:managebudget.php?e=1pid=$pid); *should* be executed...
but it isn't. (Weirdly, if I put a die() command *after* this header()
command, it works... but it seems pathologically inelegant to do so.)
There's nothing in wrong in putting a die command after the
header(Location). In fact, it is common. The header() command by
itself don't imply in the send of the request. You can have many
header() commands in sequence, and the header will be sent only in the
end of the process.

For one thing, I'd put a space after Location: in the header() call.
But I've found that this call will sometimes fail (or *look* like it
fails) unless you put something like exit(); after it. This terminates
execution and forces the script to transfer control as it should. Just
make it a habit to always include and exit(); call after your final
header() call.

Just make your life easy and create a redirect() function that generates
the header instruction, makes a relative URL into an absolute URL and
does the exit call. Then you just need to do:
redirect( 'target.php' );

Hi PHP people
I have a really strange and annoying problem. I've got a site, where
members can download music. User clicks index.php (in index.php
there's an iframe, that opens another file), if certain check are okay
then a popup window opens download.php, where a mp3 file is fetched
from the server and renamed in the header, then pushed to the enduser,
this works fine. But now I want to create zipfiles too but when a user
downloads a zipfile it's like the whole site is freezed until download
has completed. My guess is that this is some sort of header problem
(see headers below), due to three headers at the same time, cause the
class works as expected in the test page i've created. Inputs to
correct headers would be appriciated very much :-)
Mp3 headers:
$new_filename = attachment; filename=\{$artist} - {$title}.mp3\;
header('Content-Description: File Transfer');
header(Content-Type: application/octet-stream);
header(Content-Length: $size);
header(Content-Disposition: $new_filename);
header(Content-Transfer-Encoding: binary);
readfile($source_file);
Zip headers:
$zip = new zipfile();
$zip-add_dir(.);
$new_filename= {$artist} - {$title}.mp3;
if(mysql_num_rows($result)) {
$zip-add_file($file, $new_filename);
}
header(Pragma: public);
header(Expires: 0);
header(Cache-Control: must-revalidate, post-check=0, pre-check=0);
header(Cache-Control: private,false);

It's still not the ultimate solution as we wanted the zipfile to be created on the fly in memory in order not to have to delete files afterwards and to be sure that only allowed users can fetch the files (of course you can always put the zipfiles outside webscope, but still...) -- Kind regards Kim Emax -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Header problem
Andrea Giammarchi wrote on 2009-10-03 13:40:
Do you want users download the file or the zip?
They can choose between the two.
do you send other headers before the download?
Header must come first (before you output anything) or you get a parse
error, so I'm not sure what you mean here? You can see the source of the
class at the testpage I linked to.
It's quite a common error to set a default header in PHP at the
beginning of whatever application, while header should be used as last
exit point and never in the middle, or at the beginning, of a response.
I'm not sure what you mean by this? My download.php first checks for the
relevant data is there (track_id/version_id, a session with member_id),
then if the download is allowed (by access or if it has already been
downloaded) then it fetches the relevant files, zip these to the disk
and first then... creates the zip header and afterwards uses a readfile
on the zipfile just created.
Moreover, if you use readfile and then zip what do you expect,
multiple downloads in one? This is not how HTTP work ... so please show
more php, or explain better what you would like to do.
What do you need to see besides the testpage?
If I have 4 mp3 files of 5mb each, these will be zipped into one 20mb
file, and that is of course only one download. That's the wish from the
siteowner: easier download of several mixes of the same artist/track
I hope this makes the problem more clear to you :-)
I've debugged some more into the problem, this is a header of a zip
download where the site works as expected:

I call the file like this: index.php?get_zip=test_output.zip
index.php does this:
$new_zipfile .= $_SESSION['download_title']..zip;
/*
header(Cache-Control: no-cache);
header(Pragma: no-cache);
header(Expires: now);
*/
header('Accept-Ranges: bytes');
header(Content-Type: application/zip);
header(Content-Length: .filesize($archiveName));
header(Content-Disposition: attachment; filename=\$new_zipfile\);
header(Content-Transfer-Encoding: binary);
readfile($archiveName);
exit;
The outcommented headers was put in because I discovered that the
download then was cached after giving the file a strange name, that name
never occured in the download :-/ I've ended up by making a workaround
by adding nocache=.microtime(). to the get_zip link but then the site
freezes againg during the download, arrrghh...
And headers from the original zip solution in download.php, headers are
set in function.inc, this is the output from Live HTTP headers:

difference to the returned zip headers in index.php is pragma,
cache-control and expires, so I've removed these headers from the
function, but they still show up:

RE: [PHP] Header problem
Afaik, the content length header is not necessary, but it will cause problems if it's set and it's wrong. correct, missed Content-Length means the classic download with useless progress bar and undefined estimation time, problematic for preloader as well in case of images, swf, generic data, etc. Content_length should be always present and it should be correct, but obviously if there are print or echo or other outputs non file related, Content-Length can simply mess up the response. _ Windows Live: Friends get your Flickr, Yelp, and Digg updates when they e-mail you. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_3:092010

with print something ... but there is no exit after the download, so the zip
will have extra output included without a reason ... which is an error, imho,
dunno how else explain if you can't see your print links at the end of the
page ...

Hello Andrea

Header must come first (before you output anything) or you get a parse
error
I try to better explain ...
HTTP works like this: you ask something, you receive something, html and
texts are just one option.
Got it so far
Your example page mess up html, zip, everything, because when you
download a file you still have the rest of the page sent in the output.
Nops, not really.
index.php:
print stuff
do stuff
open download.php in a _new_ window.
print more stuff
page end
this should be possible, right? Two different headers for two different
pages.
A download should have ONLY file related info/headers and nothing else
in the output ... echo/print in the middle of the code before an header
is an error, everything in output before an header is an error,
everything after headers that is not related to that header is an error,
got my point?
Jep! And that's actually what I do. What I could, is to add exit; after
the headers have been sent and the file have been pushed. I do an update
of the database to tell the system that the files in the zipfile has
been downloaded.
To decide how a page should behave, you must be able to do not produce
anything except the expected output with expected headers, that's why I
have said headers are fundamental for a response, we cannot play with
outputs however we want.
The only output is the headers of the zipfile:
header('Accept-Ranges: bytes');
header(Content-Type: application/zip);
header(Content-Length: $size);
header(Content-disposition: attachment;
filename=\.basename($zip_filename).\);
header(Content-Transfer-Encoding: binary);
readfile($filename);
// we need to reload top5 to have a current view
unset($_SESSION['top5']);
$_SESSION['reload_top5'] = 1;
// NOTE second param shall be an array, not a variable when
downloading zip files
download_completed($member_id, $downloaded_version_ids);
Wouldn't you say this is okay?
As summary, once you have created and tried a dedicated page without a
single white space or print before, during, or after the dedicated
download stuff, I'll try to understand where is the error.
Otherwise it could be everything, and I am against magic behaviors ...
you need to download? Well, create a file which aims id to download and
nothing else, or you gonna constantly find these kind of problems in
your applications.
I believe the testpage does forfill that request? Or do you mean otherwise?
Kind regards
Kim

RE: [PHP] Header problem
Do you want users download the file or the zip?
do you send other headers before the download?
It's
quite a common error to set a default header in PHP at the beginning of
whatever application, while header should be used as last exit point
and never in the middle, or at the beginning, of a response.
Moreover,
if you use readfile and then zip what do you expect, multiple downloads
in one? This is not how HTTP work ... so please show more php, or
explain better what you would like to do.

Subject: [PHP] Header problem
Hi PHP people
I have a really strange and annoying problem. I've got a site, where
members can download music. User clicks index.php (in index.php
there's an iframe, that opens another file), if certain check are okay
then a popup window opens download.php, where a mp3 file is fetched
from the server and renamed in the header, then pushed to the enduser,
this works fine. But now I want to create zipfiles too but when a user
downloads a zipfile it's like the whole site is freezed until download
has completed. My guess is that this is some sort of header problem
(see headers below), due to three headers at the same time, cause the
class works as expected in the test page i've created. Inputs to
correct headers would be appriciated very much :-)
Mp3 headers:
$new_filename = attachment; filename=\{$artist} - {$title}.mp3\;
header('Content-Description: File Transfer');
header(Content-Type: application/octet-stream);
header(Content-Length: $size);
header(Content-Disposition: $new_filename);
header(Content-Transfer-Encoding: binary);
readfile($source_file);
Zip headers:
$zip = new zipfile();
$zip-add_dir(.);
$new_filename= {$artist} - {$title}.mp3;
if(mysql_num_rows($result)) {
$zip-add_file($file, $new_filename);
}
header(Pragma: public);
header(Expires: 0);
header(Cache-Control: must-revalidate, post-check=0, pre-check=0);
header(Cache-Control: private,false);
header(Content-type: application/zip);
#header(Content-Type: application/octet-stream);
header(Content-disposition: attachment; filename=\zipTest.zip\);
header('Content-Transfer-Encoding: binary');
ob_end_clean();
echo $zip-file();
Code example: http://lps.netlinq.dk/test010/test_zip.class.php
Headers (fetched with firefox add-on: live http headers)
This is headers from the site, where the problem occurs:
1. click on the link to a title (Maxwell in this case)

Re: [PHP] header problem
Hi Blueman. As soon as ANYTHING has been drawn to the browser, you
cannot use a header command. So you need to work through all of your
code, and ensure that all of your logic that could result in a header
call is run BEFORE you send any html code. Is going to be tricky if
mixing html and php calls.

The problem you have is not that you need to work around this 'problem'
in PHP, but you need to fix your broken code. This problem often comes
up on the list, and is usually because of extra whitespace in include
files, or errors being output to the browser which force the headers to
be sent.

Don't use a timer to redirect if you want the user to read a message, as
this assumes that the visitor is a good reader. This is forgetting all
of those visitors with reading difficulties (i.e. Dyslexia), those users
who have attention problems who can't focus on text for long periods
(i.e. ADHD) and any users who rely on things such as screen readers
(which are slower than reading text yourself (if you're an average
reader!) ) or a Braille browser.
In cases such as these, it's best to let the visitor move at their own
pace and not redirect until they want to.

Subject: [PHP] header problem
hello
I recentrly uploaded my project from localhost to a hosting and found many
errors and warnings which didnt have in local. one of the most annoying one
is header('Location xxx').
I have used header to redirect users from pages, and kinda used it alot. i
know about the whitespace causing warning, but most of the pages i'm sending
users got html and php mixed so i'm confused about how to remove whitespace
in a html/php file. the error is :
Warning: Cannot modify header information - headers already sent by
here is a simple example, user update page :
if($valid)
{
$msg='111';
$user-dbupdate();
header(Location: /admin/index.php?msg=$msg);
}
else
{
foreach($errors as $val)
echo 'p id=error'.$val.'/p';
}
and on admin index i get $msg and display it.
html
..
//lots of stuff
?php
$msg = $_GET['msg'];
switch($msg){
case '111' echo 'p /p';
break;
case '421':...
}
?
// more html and php
how can i fix this?

It's possible that on your localhost you have output_buffering set on either
in php.ini or in a .htaccess, which would avoid the displayed error about
headers. If it's switched on locally and off for your host server then
you'll get the problem you reported. Check that this is off locally (use
phpinfo) so that you can be sure your code is working properly before you
upload.
Alternatively if you want to be able to do a redirect after you've already
started your output (this is sometimes done for error handling) you could
use ob_start() to start output buffering, ob_end_clean() to clear the output
buffer and start again, and ob_flush() to send the output buffer. If you
want to continue using output buffering after an ob_end_clean() you'll have
to do an ob_start() again.
Cheers

RE: [PHP] header() and passing sessions
Date: Wed, 15 Apr 2009 11:09:19 -0500
From: awill...@mdah.state.ms.us
To: php-general@lists.php.net
Subject: [PHP] header() and passing sessions
I need some help passing a session variable with a header() function.
According to www.php.net/header, the documentation states:
*Note*: Session ID is not passed with Location header even if
session.use_trans_sid
session.configuration.php#ini.session.use-trans-sid is enabled. It
must by passed manually using *SID* constant.
so, I'm trying to manually pass the SID, but not having any luck. Here
is a snippet of my code:
There is a file login.php which has session_start(); and sets
$_SESSION[username] with the username you logged in with from
index.php and has a form to click View Pending Requests which has the
action of option.php.
-- option.php --
?php
session_start();
if ($_POST[option] == View Pending Requests)
{
header('Location:
http://intra.mdah.state.ms.us/helpdesk/viewpending.php?PHPSESSID='.session_id());
}
?
--viewpending.php --
?php
session_start();
if (!$_SESSION[username])
{
echo You have not logged in;
exit;
}
?
so you click on View Pending Requests, and the URL in your browser is:
http://intra.mdah.state.ms.us/helpdesk/viewpending.php?PHPSESSID=du75p41hel9k1vpuah799l2ce7
but viewpending.php says You have not logged in. Why is that?
Hi,
Well I'ld say the reason is quite obvious. You have simply not set
$_session[username] . I'ld have done something like:
-- option.php --
?php
session_start();
if ($_POST[option] == View Pending Requests)
{
$_session[username]= true; //sets the session
header('Location:
http://intra.mdah.state.ms.us/helpdesk/viewpending.php?PHPSESSID='.SID);//
I'ld use SID
}
?
--viewpending.php -
?php
session_start();
if ($_SESSION[username] !=true)
{
echo You have not logged in;
exit;
}
?
I hope this helps. try it.

Well the thing is, $_SESSION[username] is set. If I change option.php to:
?php
session_start();
echo session username is .$_SESSION[username];
/*if ($_POST[option] == View Pending Requests)
{
header('Location:
http://intra.mdah.state.ms.us/helpdesk/viewpending.php?PHPSESSID='.session_id());
}
*/
?
and click on View Pending Requests, it prints:
session username is awilliam

Hi Bastien - Stuart Daniel
Thanks for your help!
On 3/10/2009 12:16 PM, Bastien Koert phps...@gmail.com wrote:
Are you getting an error? What does 'not working' mean?
No errors the page just stayed on the
header('Location: show.php'); page - never went to: show.php
One more thing to mention: The HTTP Protocoll requires you to give a
full URL on Location Headers. That means that this is wrong:
Location: file.txt
and this is correct
Location: http://www.x.x/file.txt;
Not all clients behave like yours and accept the wrong header.
Q: I might have learned something Does the: header('Location: xxx.php');
command need to be in the first php block? On some pages when I make multi
php blocks into 1 big one and put the header command inside it - it seems to
work better - is this true?
All HTTP headers must be send before your script generates *any* output.
Output means echo's, PHP Notices, etc.
If you *must* output stuff before sending an header, you can use
output buffering, see http://php.net/ob_start
Q: Also, is it possible that extra whitespace inside the php block can cause
the header command to not work? (I might have that happening also - looking
into it)
Yes, *any* output - no matter if you output or x or even :-).
Well, if the above is in fact the case (and yes, different
versions and installations have been known to respond differently),
then you can use a browser-based meta refresh, which will work for all
browsers anyway:
unless disabled by the user.
?php
// your code
header('Location: show.php');
echo 'meta http-equiv=refresh content=0;show.php';
erm META should be in a html document inside the HEAD, not *anywhere*.
I tried refresh Daniel - and it worked great!
I even added a GET var to it - worked also
echo 'meta http-equiv=refresh content=0;show.php?id='.$_GET[id].'';
Very, very, very bad idea. You just opened a cross site scripting bug.
Imagine someone opens this URL
host/yourfile?id=scriptalert(document.cookie)/script
You must always escape any input you take.
see http://php.net/security
Thanks again folks!
You're welcome.

Did you already have some output sent to the browser? That may be
causing header() not to be able to send the Location header to the
browser properly.

This kills three birds with the same stone like so:
1.) It tries to use the header() location redirect.
2.) It falls back on browser-based redirection.
3.) It forces a flush() of the data to the client, regardless
of minimum size limits.
4.) It forces the script to exit with a non-error code of 0.

Re: [PHP] Header() - POST
I actually just completely re-engineered this page. It made sense reading what everyone had to say. The extra page that I wanted to post to was really not needed. I have everything just contained in the one php script now, and its working perfectly that way. After it submits the order, it then redirects to a confirmation page, rather than trying to validate, rebuilt the post string, and then submitting that to another page for processing and confirmation. Just made more sense really. In the future, though, if I find I need to do this, curl seemed to be the best option. I've used javascript in the past to do it, but it seemed messy to me. -- -Dan Joseph www.canishosting.com - Plans start @ $1.99/month. Build a man a fire, and he will be warm for the rest of the day.

404
handling with fuzzy request sniffing to determine what was actually
requested, I again perform a redirect once I've ascertained what was
probably desired. If you don't, then Google and other search engines
will index these malformed URLs instead of the correct URL.
The correct response to a 404 page is 404. No arguments. If you
redirect missing pages then your site effectively contains an
infinite
number of pages. By all means display a useful page when you return
your 404 but not marking it as a missing page does little if anything
for your SEO rank and absolutely nothing for your users.
404 Not Found, but it was found, but it's not where you asked for
it,
it's over there... we've permanently moved it from here to there (even
if only virtually)... let's redirect you to the correct location.
Since
you perform a redirect to the correct location, the content is
appropriately indexed where it actually exists. If you return a 404
status I'm pretty sure Google discards the content.
If you can successfully fulfil the request then it's not a 404, but I
would question why you're getting requests for URLs that don't exist
but that you can accurately service. If you're using the URL as a
search field then your site truly has no missing pages.
However, in that case it's unlikely you'll be redirecting since for a
lot of queries you'll end up with multiple results meaning you're not
accurately fulfilling the request unless there's only one result from
the search. In that case I would agree that a redirect is the done
thing - except where the user got there by doing a search, which is
where things get cloudy as some would say it's appropriate to show
search results since that's the reasonable user expectation, and
others would say it should redirect to the single result - where I'd
come down on that would depend on the content and average user profile.
*breath!*
If you return a 404 Google does indeed discard the content - that's
the logical thing for it to do. 301's allow it to reduce the URLs
used to access your site to a core set of real content. Given that,
I agree to your premise that if you can successfully fulfil the
request by redirecting then you should, but only if it's an accurate
response to the request and not a best guess. Best guesses should be
presented to the user (and Google) as a page suggesting content and
providing other ways to find it if your suggestion is not correct.
I'm starting to ramble so I'll stop here. I hope the point I'm making
is clear in there somewhere.
IMHO if you're going to use a semantic argument to defend one point
you need to carry that attitude throughout.
My semantic argument is still intact. If I found it, then it's not
deserving of 404 Not Found status. Sure it may not be at the
requested
location, but that's what the moved status is for.
The 301 status code was created so web developers can re-organise
their websites without adversely affecting the user experience. A side
effect of this is that search engines also use them to keep their
index up to date without affecting the sites ranking.
Here's a physical world analogy. Walk into a hardware store ask for

The correct response to a 404 page is 404. No arguments. If you
redirect missing pages then your site effectively contains an infinite
number of pages. By all means display a useful page when you return
your 404 but not marking it as a missing page does little if anything
for your SEO rank and absolutely nothing for your users.

it's over there... we've permanently moved it from here to there (even

My semantic argument is still intact. If I found it, then it's not
deserving of 404 Not Found status. Sure it may not be at the requested
location, but that's what the moved status is for.
Here's a physical world analogy. Walk into a hardware store ask for
object X. If they have it they will tell you. If they don't then either
they will say, Sorry, we don't have that. I don't have a clue where you
can get it, or if they do know (and want to help) they'll say It's
over there at Rob's Hardware Store. What they almost certainly won't
say is hang on, then run over to Rob's hardware Store, buy item X, come
back and try to sell it to you. Almost certainly, but who knows, people
do weird things sometimes :)
So here's something else since you played the performance card. Click on
the following link and tell me where you end up when not already logged
in:
http://mail.google.com/mail/
I'm sure Google had a good reason for that behaviour, as in it's follows
more correctly the standard expected request behaviour, and I'm sure
they get a LOT of hits ;)

Since
you perform a redirect to the correct location, the content is
appropriately indexed where it actually exists. If you return a 404
status I'm pretty sure Google discards the content.
If you can successfully fulfil the request then it's not a 404, but I
would question why you're getting requests for URLs that don't exist
but that you can accurately service. If you're using the URL as a
search field then your site truly has no missing pages.
However, in that case it's unlikely you'll be redirecting since for a
lot of queries you'll end up with multiple results meaning you're not
accurately fulfilling the request unless there's only one result from
the search. In that case I would agree that a redirect is the done
thing - except where the user got there by doing a search, which is
where things get cloudy as some would say it's appropriate to show
search results since that's the reasonable user expectation, and
others would say it should redirect to the single result - where I'd
come down on that would depend on the content and average user profile.
*breath!*
If you return a 404 Google does indeed discard the content - that's
the logical thing for it to do. 301's allow it to reduce the URLs
used to access your site to a core set of real content. Given that,
I agree to your premise that if you can successfully fulfil the
request by redirecting then you should, but only if it's an accurate
response to the request and not a best guess. Best guesses should be
presented to the user (and Google) as a page suggesting content and
providing other ways to find it if your suggestion is not correct.
I'm starting to ramble so I'll stop here. I hope the point I'm making
is clear in there somewhere.

My semantic argument is still intact. If I found it, then it's not
deserving of 404 Not Found status. Sure it may not be at the
requested
location, but that's what the moved status is for.
The 301 status code was created so web developers can re-organise
their websites without adversely affecting the user experience. A side
effect of this is that search engines also use them to keep their
index up to date without affecting the sites ranking.

Best regards,
From the HTTP RFC:
The Location response-header field is used to redirect the recipient to
a location other than the Request-URI for completion of the request or
identification of a new resource. For 201 (Created) responses, the
Location is that of the new resource which was created by the request.
For 3xx responses, the location SHOULD indicate the server's preferred
URI for automatic redirection to the resource. The field value consists
of a single absolute URI.
Location = Location : absoluteURI
Your script doesn't appear to be trying to do a re-direct, but rather open a
client side e-mail - if you want to do this, then you will need to use
JavaScript on the client side.
HTH,
