Summary: '200 OK' HTTP status despite PHP error
Status: Re-Opened

Also - output buffering is enabled by default, no? So doesn't matter if output already sent,
the status code can be overridden surely?
And again, even if headers already sent, at least get the string '500 Internal Server
Error' (as would happen if display_errors was off) into the output so the user has some clue
something went wrong. How does displaying *less* error information if
'display_errors=true' make any sense? ;)

Disagree with above commenter - HTTP status codes are *designed* for monitoring the status of web
services. Saying check the logs assumes the user has access to the logs - could be a shared host
without log access, a third-party's service, or monitoring from an external uptime checker.
Sure - if headers have already been sent, not a lot PHP can do about that (though a basic HTTP 500
warning message would be better than the current blank page). But at the moment it doesn't
matter if headers have been sent or not - PHP fails to return the correct 500 status code, which
just about every other stack manages just fine.
After reporting this over 5 years ago, and it was known long before that, I'm at loss how
something so basic hasn't been fixed yet.

You can't completely fix this by the way http works.
<?php
echo 'x';
ob_flush(); // http status code and headers are now sent to client
eval('x=y'); // error detected here
no matter which technology stack, after you've sent everything is 200 OK you can't signal
the client something went wrong. You shouldn't monitor your service through status codes only
because of this edge case. Monitor your logs.

I can't believe this hasn't been solved yet. It has been more than 5 years people! RFC
2616 is very clear on proper HTTP status codes
(http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html). If some obscure browser handles return
codes improperly, that should be solved there, not in PHP. This is not 1990s anymore, IE is far from
being a dominant browser anymore.
So how about fixing this the right way? Just return status 5xx on parsing and similar errors, as
recommended (SHOULD) by HTTP 1.1 protocol. It shouldn't be that difficult.

Not just display_errors = off. I believe this effects display_errors =
stderr as well for similar reasons.

I would agree that this is a bug. If there has been a server error, we should not be returning a 200
response. If IE then does not display it, that is a problem for IE to look at. The wrong header
causes a lot of problems, especially for AJAX>
