Bug->Doc #75009 [Nab->Ver]: http_response_code() error code support depends on SAPI

Edit report at https://bugs.php.net/bug.php?id=75009&edit=1 ID: 75009 Updated by: requinix@php.net Reported by: czirkos dot zoltan at gmail dot com -Summary: http_response_code() fails on nonstandard error code +Summary: http_response_code() error code support depends on SAPI -Status: Not a bug +Status: Verified -Type: Bug +Type: Documentation Problem Package: Apache2 related Operating System: Linux 4.4.0-62-generic #83-Ubunt PHP Version: 7.0.21 Block user comment: N Private report: N New Comment: #116880 is partially correct in that PHP does use that list, but it's only for php-fpm, the built-in dev server, and when running as regular CGI (as far as I can see). A note along the lines of http://php.net/manual/en/function.http-response-code.php#114996 that support depends on the SAPI and how to use header() as a workaround for non-standard codes would be a good idea. Previous Comments: ------------------------------------------------------------------------ [2017-07-31 15:00:44] czirkos dot zoltan at gmail dot com Thank you for the clarification. It might be a good idea to mention this in the documentation; something like "Available response codes depend on the server software used". There's a comment about that (http://php.net/manual/en/function.http-response-code.php#116880), but this is more important than that. ------------------------------------------------------------------------ [2017-07-31 14:42:50] requinix@php.net http_response_code() depends on the SAPI (Apache or FPM+nginx) supporting the code. nginx doesn't mind a custom 210 but Apache does and it (not PHP) substitutes a 500 instead [1]. If you want a custom status then use header(), which Apache handles differently than if you just give the code. header("HTTP/1.1 210 Whatever That Code Means"); [1] They support 200 OK through 208 Already Reported. Anything 2xx above that will be rejected. See their modules/http/http_protocol.c for more. https://svn.apache.org/viewvc/httpd/httpd/branches/2.4.x/modules/http/http_protocol.c?revision=1799890 ------------------------------------------------------------------------ [2017-07-31 07:17:06] czirkos dot zoltan at gmail dot com Description: ------------ The http_response_code() function fails for a nonstandard error code (eg. 210). 500 Internal Server Error is emitted instead. This only happens with the apache2handler SAPI; eg. Nginx+FPM works fine. Test script: --------------- http_response_code(210); echo "hello"; Expected result: ---------------- Proper error code sent via the server. Please not that documenting the list of error codes (in the documentation at http://php.net/manual/en/function.http-response-code.php) is not really a solution, as custom error codes can be defined. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75009&edit=1
