Req->Bug #78844 [Opn]: FPM does not support multiple HTTP request headers with the same name

Edit report at https://bugs.php.net/bug.php?id=78844&edit=1 ID: 78844 Updated by: requinix@php.net Reported by: mikk150 at gmail dot com -Summary: Ability to get all client sent HTTP headers +Summary: FPM does not support multiple HTTP request headers with the same name Status: Open -Type: Feature/Change Request +Type: Bug -Package: *Web Server problem +Package: FPM related Operating System: Linux PHP Version: 7.3.11 Block user comment: N Private report: N New Comment: The ability to get headers is highly dependent on the SAPI. Apache's works nicely, but php -s is just a quick development server that is not going to be suitable for all purposes. So really, the issue here is that php-fpm doesn't properly handle multiple headers. The HTTP spec requires that multiple headers only be allowed when their values can be combined into comma-separated lists, which means $_SERVER and getallheaders() are still sufficient.

If you have multiple header lines with same name, each SAPI does totally different thing(and all of them are wrong) If I make request: GET / HTTP/1.1 Forwarded: for=10.0.0.1,for=20.30.40.50;host=php.net,host=awesome.proxy.com;proto=https,proto=http Forwarded: for=10.30.20.10;host=second.awesome.proxy.com;proto=http I get 3 different responses based on SAPI FPM only keeps last header php -s only keeps first header apache concatenates them with , PHP should implement new method to get all headers OR implement some class that has method to get all headers ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78844&edit=1
