At the top of your script add:

<?php
error_reporting (E_ALL);
ini_set('displa y_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'.

PHP: header - Manual

http://uk.php.net/header

Send a raw HTTP header

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

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

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.

Yes, I guess my server is somehow misconfigured.

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.

Re: Header Redirect Bug

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_fi rst_header");
header("Locatio n: http://www.example.com ");
touch("after_se cond_header");

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

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