From: [EMAIL PROTECTED] Operating system: Win32 (XP) PHP version: 4.1.1 PHP Bug Type: Output Control Bug description: header() does not replace headers but always produces duplicates
>From the docs: The optional "replace" parameter indicates whether the header should replace a previous similar header, or add a second header of the same type. By default it will replace, but if you pass in FALSE as the second argument you can force multiple headers of the same type. At least with PHP 4.1.1/Win32(XP), this is NOT true - headers are always added up. Using this little test: <?php header('X-Test-Header: Version 1'); header('X-Test-Header: Version 2'); ?> this output is created: ------------------------------------- php headers.php X-Powered-By: PHP/4.1.1 X-Test-Header: Version 1 X-Test-Header: Version 2 Content-type: text/html ------------------------------------- According to the docs, only "Version 2" of the header should be sent. The results are identical if you do not provide the "replace" parameter, or if you set it to true or false. This is a very annoying bug, and for my application I'd rate it "critical". -- Edit bug report at http://bugs.php.net/?id=16458&edit=1 -- Fixed in CVS: http://bugs.php.net/fix.php?id=16458&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=16458&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=16458&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=16458&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=16458&r=support Expected behavior: http://bugs.php.net/fix.php?id=16458&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=16458&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=16458&r=submittedtwice
