Sending headers to server

[Miguel Guedes]

Hello List,


I'm running PHP 5.4.9 as CGI (via apache 2.2.22) and can't seem to be
able to send headers to the server.

Both,

header('Status: 500 Internal Server Error');

and,

header('HTTP/1.1 500 Internal Server Error', true, 500);

result in nothing happening on the client side.

What am I missing?

Works for me. What happens exactly? Do you get a 200?

That's exactly right - I always get a 200. How can I diagnose this?

Try getting the complete header by using curl -v http://url.com and
paste it here. In my example I'm getting this output:

* About to connect() to ****** port 80 (#0)
* Trying 213.***.***.***...
* Connected to ****** (213.***.***.***) port 80 (#0)

GET /test.php HTTP/1.1
User-Agent: curl/7.29.0
Host: ******
Accept: */*

< HTTP/1.1 500 Internal Server Error

< Server: Apache
< Content-Length: 6
< Connection: close
< Content-Type: text/html; charset=UTF-8

* Closing connection 0

What is your output?

Here's my output:

$ curl -v http://localhost/header-test.php
* About to connect() to localhost port 80 (#0)
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 80 (#0)

Using the following test script:

<?php

header('Status: 500 Internal Server Error');
header('HTTP/1.1 500 Internal Server Error', true, 500);

?>

allright, that's weird. I'm currently not able to reproduce your problem
but I've found out that some others are experiencing the same problem
like you do. They found this solution to work:
header($_SERVER["SERVER_PROTOCOL"] . 'HTTP/1.1 500 Internal Server Error');

Might try this one..

This is strange. I've just found out that the headers are sent
correctly if I access the website outside of localhost. I don't
understand why.

I also don't. I've tried the exactly same code you posted on my
localhost as well and it worked all properly. Weird behaviour, can
anyone explain why this happens?

Could it be that you're actually ending up with a different site because
you have configured your vhost to a certain domain?

Did you print some data before using header?

No, not at all. I've PHP configured to complain about notices, warnings
and errors; would've got a warning about headers already sent, which I
don't get.
