Summary0000532: XDebug breaks header() function
DescriptionI use:
  - Windows 7 RC
  - PHP 5.3.1
  - php_xdebug-2.1.0beta2-5.3-vc6.dll

And the following PHP code:
<?php
header('Content-Type: text/plain; charset=UTF-8');
echo 'This is plain text HTML tags should be visible:

';


Expected result is the following HTTP header:
Content-Type: text/plain; charset=UTF-8


Actual result is this:
Content-Type: text/html


Screenshots:
With php_xdebug-2.1.0beta2-5.3-vc6.dll (buggy Content-Type header, X-Powered-By header gone too):

With php_xdebug-2.0.5-5.3-vc6.dll (WORKS PROPERLY):

Confirming the above - I'm having the very same issue using the following setup:

- Windows 7, x64
- Apache 2.2.14 (VC9, from http://www.apachelounge.com/download/)
- PHP 5.3.1 (VC9, from php.net)
- php_xdebug-2.1.0beta2-5.3-vc9.dll
- basic xdebug configuration:
  xdebug.remote_enable=true
  xdebug.remote_host=127.0.0.1
  xdebug.remote_port=9000
  xdebug.remote_handler=dbgp
- basic debugging works fine (Netbeans 6.8)

It looks that no HTTP headers from PHP reach the browser (even the X-Powered-By header is missing) - this way location headers or content type charset settings don't work at all.

I'm also experiencing this issue (obviously cookies / cookie based sessions don't work correctly without headers)

Exactly the same setup as jotta, with code that boils down to:
<?php
setcookie('test', 'hello world', 0);

var_dump($_COOKIE['test']);

Expected Result:
string(11) "hello world"

Actual Result:
Notice: Undefined index: test

Issues goes away when xdebug is not loaded.

Good news, I can reproduce this (With Apache from apache.org, and PHP 5.2.13dev VC6 with Xdebug 2.1.0beta3-dev). Bad news, no clue why this happens yet :-)

Expecting same bug on Windows 7 RTM Professional 32-bit with php 5.3.1 VC9 and xdebug beta2. I hope it will be fixed soon, because it is so boring to work without debug =(

I was be able to reproduce this on Linux in a threaded environment as well, and I've just uploaded new Windows binaries to http://xdebug.org/files/xdebug-latest.tgz which should contain a binary that has this issue fixed. Could you please verify this as well? (The binaries should also fix another crash bug)

Variables in local scope (0000002) are all still reporting as undefined.

Closing, as this seems fixed now.

@mpanciera contact me through the mailinglist with a remote debug log (See http://xdebug.org/docs/remote#remote_log on how to make one)
