#33225 [Opn]: PHP sends multiple Status headers

ID: 33225 User updated by: phpbugs at thequod dot de Reported By: phpbugs at thequod dot de Status: Open Bug Type: Documentation problem Operating System: * PHP Version: 5.0.4 New Comment: Sniper, please use a FastCGI-compiled PHP-CGI binary and don't inspect the Apache output. If you would have been running php-fastcgi on your Apache2 server you would've gotten a "Internal server error", because fastcgi dies on multiple Status headers. It's not only a documentation problem, but causes Internal Server errors with Apache and fastcgi, because fastcgi is very strict about the "There has to be exact one status code in the cgi response". Previous Comments: ------------------------------------------------------------------------ [2005-06-03 23:18:04] sniper@php.net Here's what I get with Apache2 and your script: HTTP/1.1 302 Found Date: Fri, 03 Jun 2005 21:15:54 GMT Server: Apache/2.0.52 (Fedora) X-Powered-By: PHP/5.1.0-dev Status: 301 Location: http://www.example.org Connection: close Content-Type: text/html; charset=ISO-8859-1 IMO, this is not a bug in either SAPI. Just documentation issue. ------------------------------------------------------------------------ [2005-06-03 01:56:26] phpbugs at thequod dot de Description: ------------ Multiple "Status" lines get send when using "header('Location: url')", which produces an additional 302 (REDIRECT) status code. This causes FastCGI (at least) to produce a 500 Internal Server Error: FastCGI: comm with server "/path/to/fcgi-starter" aborted: error parsing headers: duplicate header 'status' Documentation (http://us2.php.net/manual/en/function.header.php) says: Note: The HTTP status header line will always be the first sent to the client [[NOT TRUE! - reproduce: echo "<?php header('Status: 304'); ?>" | php5/bin/php-fcgi]], regardless of the actual header() call being the first or not. The status may be overridden by calling header() with a new status line at any time unless the HTTP headers have already been sent [[NOT TRUE! - this bug]]. ----------------------------------- configure (both PHP5 and PHP4): ./configure --enable-memory-limit --enable-force-cgi-redirect \ --enable-track-vars --with-pcre-regex --with-mysql --without-sqlite \ --with-zlib --with-bz2 --enable-mbstring --with-openssl --enable-exif \ --with-dom=shared --with-ttf=shared --with-gd=shared --enable-calendar \ --with-iconv --enable-inline-optimization --enable-gd-native-ttf \ --with-ldap --with-ldap-sasl \ --with-gettext \ --without-mm --enable-fastcgi --prefix=/home/daniel/php5 Reproduce code: --------------- $ cat << "?>" | php5/bin/php-fcgi <?php header( 'Status: 404' ); header( 'Status: 301' ); header( 'Location: http://www.example.org' ); ?> Expected result: ---------------- Status: 301 Content-type: text/html X-Powered-By: PHP/5.0.4 Location: http://www.example.org Actual result: -------------- Status: 302 Content-type: text/html X-Powered-By: PHP/5.0.4 Status: 301 Location: http://www.example.org ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33225&edit=1
