#18824 [Bgs]: PHP should produce an appropriate status code when an error is encountered

ID: 18824 Updated by: rasmus@php.net Reported By: bugs.php.net@mnot.net Status: Bogus Bug Type: Feature/Change Request Operating System: unknown (maybe FreeBSD?) PHP Version: 4.2.2 New Comment: No, buffering is not that common. But even so, having the http status change depending on buffering would be quite inconsistent and would likely confuse the heck out of people. Also, consider that errors generally occur after some valid content has been generated, and not sending this in a valid response would make it considerably harder to debug things. If someone wants this functionality in buffered mode, they could easily do it with their own error handling function. Previous Comments: ------------------------------------------------------------------------ [2002-08-09 02:31:02] bugs.php.net@mnot.net So is the correct status code output if the response is buffered? AFAIK a fair number of PHP applications use output buffering these days, so it would be useful to take advantage. ------------------------------------------------------------------------ [2002-08-09 02:15:54] rasmus@php.net You are assuming that PHP buffers all output before sending anything. That is an incorrect assumption. A fatal script error can occur long after the HTTP response headers have been sent. ------------------------------------------------------------------------ [2002-08-09 02:09:32] bugs.php.net@mnot.net I don't use PHP, I'm just a protocol weenie. I encountered the following from travel.yahoo.com tonight: HTTP/1.1 200 OK Date: Fri, 09 Aug 2002 06:02;01 GMT Connection: close Content-Type: text/html <br /> <b>Fatal error</b>: Cannot instantiate non-existent class: travel in <b>/home/y/share/htdocs/t/index.php</b> on line <b>19</b><br /> Fine, except that it gives a 200 OK status. The right thing would be to generate a 500 Server Error status; this indicates that something is wrong in a machine-understandable way, which is good. It shows up in the logfiles. Agents (like Google) understand that all is not well. Please modify PHP to generate appropriate status codes. 500 is just one example; have a look at RFC2616 for other status codes that you might want to map machine-understandable semantics to.
