headers

+Status: Bogus
Type: Bug
Package: CGI related
Operating System: Debian Lenny
PHP Version: 5.3.3

New Comment:
PHP sends error_log() data via STDERR. RFC 3875 specifies the exact
rules as system-dependent, PHP chose to use only STDOUT for CGI
communication.

Description:
------------
A call to error_log may result in data being output before the headers,
thereby corrupting the response.
The same doesn't happen with other PHP output functions.
The ini directive error_log is set to "no value". The docs say "If this
directive is not set, errors are sent to the SAPI error logger".
Test script:
---------------
<?php
error_log("oops");
echo "content";
inexistent_function(); //fatal; no problem
Expected result:
----------------
X-Powered-By: PHP/5.3.3
Content-type: text/html
oops
content<br />
<b>Fatal error</b>: Call to undefined function inexistent_function() in
<b>/home/glopes/test.php</b> on line <b>4</b><br />
Actual result:
--------------
$ /opt/php5/bin/php-cgi test.php
oops
X-Powered-By: PHP/5.3.3
Content-type: text/html
content<br />
<b>Fatal error</b>: Call to undefined function inexistent_function() in
<b>/home/glopes/test.php</b> on line <b>4</b><br />
