Nginx sends status 200 after PHP parse error

I've configured nginx with php-fpm on Ubuntu (and everything works pretty well).

One thing I encountered is that HTTP status code 200 is sent, when a PHP parse error occurs. The error log contains the following entry:

[error] 3205#0: *2854 FastCGI sent in stderr: "PHP Parse error: syntax error, unexpected T_REQUIRE_ONCE in /var/www/.../index.php on line 32" while reading response header from upstream, client: 1.2.3.4, server: example.com; request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com"

I was not able to figure out, why not a code 50x is sent. I have not configured any error_page settin开发者_JAVA百科gs and I read the documentation of error_page. I also tried it to set the status code (with error_page 500 =500 /50x.html and so on). But always status 200 is returned.

I can send status headers from PHP (header('HTTP/1.1 404 Not Found')), this works. However, for errors issued by the PHP interpreter (also uncaught exceptions), the server's response doesn't take into account that an error occurred.

FYI, this is now fixed in Xdebug (2.2) for PHP 5.4 and up. Sadly, it needed a change in PHP to make it work that could not be back-ported to 5.3.
