Header Redirect Bug

[Philipp Lenssen]

I have a problem doing a permanent redirect. It works only if I
directly send the new location header (third line in sample below) but
never in combination with sending a "301 Moved permanently" first
(second line below). Unfortunately my server is shielding error
messages from me (and I don't have access to the PHP.INI).

------- Sample -------
<?
header("HTTP/1.1 301 Moved permanently");
header("Location: http://www.example.com");
?>
----------------------

(Note: there is no space anywhere or anything else before I send the
header. Also: I cannot send the "Moved permanently" on its own either.
It always breaks my script, but I don't know why.)

What can I do? If I redirect without 301 I'm afraid Google won't change
it's index of my pages.

Any help greatly appreciated!

At the top of your script add:

<?php
error_reporting(E_ALL);
ini_set('display_errors', true);
?>

Maybe?

<?php
header('HTTP/1.1 301 Moved permanently');
header('HTTP/1.1 302 http://www.example.com/'); // also try 307
?>

You haven't said what problem you're actually having, other than it 'breaks
your script'.

http://uk.php.net/header

What you're doing appears correct from the manual. There's also the
alternative of:

header("Location: http://www.example.com", false, 301);

That doesn't work...

I added it but still cannot see the error message other than the
default "Error occurred"...

Does the redirection work with your sample script being the _whole_
script?

Are you running php as an apache module, or as some type of CGI setup
where the web-server executes php.exe? If it's the latter, then you
can't change the HTTP response header as far ask I know. Only with the
apache module can that be accomplished.

That's part of my problem -- my server hides the error message, and I
can't turn it on.
http://uk.php.net/header

alternative of:
Yes, I guess my server is somehow misconfigured.

header("Location: http://www.example.com", false, 301);

Thanks. That at least didn't cause an error. However the page now
appeared white, and no redirect could be seen in the browser. Also if I
set the second parameter to "true".

Yes. No spaces before or after. Complete sample above pasted into
text-editor, uploaded via FTP, and run via HTTP -- Error 500 (exact
error shielded by server).

I can use the header function to redirect, however I cannot send the
301 permanent move.

I guess you mean it does *not* work.

.... have you tried switching the header()s order?

Yes, sorry got it mixed up. It does _not_ work.

Good idea. Will try.

Nope. Same 500 error.

Yea, what I was saying, is that in a CGI setup, doing a header to change
the http response will not work. Other headers will though.

header('HTTP ...'); type headers won't work unless you have the apache
module. It's noted in the manual.

[Chung Leong]

Is the script dying after the first call to header()? Run this and see which
files get created:

header("HTTP/1.1 301 Moved permanently");
touch("after_first_header");
header("Location: http://www.example.com");
touch("after_second_header");

// perhaps track_errors is on?
fwrite(fopen("php_errormsg", "w"), $php_errormsg);

Also try changing the header to "HTTP/1.0".

Thanks for trying to help. The script idea doesn't work on my
misconfigured served which I don't have complete control over. The
"php_errormsg" was created, but empty. I'm now trying to figure out how
to solve this problem right within the htaccess file, and this is my
current try:

RewriteEngine on
Options +FollowSymlinks
RewriteBase /
RewriteRule ^(.*)-([0-9]*).html show.php?title=$1&part=$2

And then someone suggested this but it doesn't quite work for me...

RewriteCond %{QUERY_STRING} ^title=([a-z]+)&part=([0-9]+)
RewriteRule ^book.php$ %1-%2? [redirect=permanent]

Any chance you can get to your error log files? Also, have you tried
threatening bodily harm to your provider's employees unless they start
showing you your rightly-deserved error messages...

Who knows, it might work... might get you thrown in jail, tho'.

Adjust your browser settings to see no-friendly HTTP message or
just use some HTTP sniffers to see the all the responses. I guess, the
script dies somewhere. May be you could post the URL of the page?

It's the error message HTML of my host... not the browser-one... but
thanks to all I officially give up on solving this with PHP and instead
try to solve it via htaccess. In fact I offer $20 at Google Answers for
a solution:
