Apache (PHP?) can't set cookies after a test with an unset variable

           Summary: Apache (PHP?) can't set cookies after a test with an
                    unset variable
           Product: Apache httpd-2.0
           Version: 2.0.43
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Major
          Priority: Other
         Component: All
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: ElfQrin@ElfQrin.com


I think this is a PHP problem, but I've submitted the bug to them first, but
they replied "Sorry, but your problem does not imply a bug in PHP itself." and
apparently think the cause might be Apache.


PHP can't set cookies on Windows 2000 systems after testing a
non-existing variable.

This problem was reported in the following conditions:
- Windows 2000 server SP-3  (IIS not installed)
- Apache v2.0.43 (confirmed on Apache v1.3.27 as well)
- PHP 4.3.0 (confirmed on 4.2.2 and 4.2.3 as well)

The problem happens with Windows 2000 only. On Windows 98 with the very
same configuration, or on Linux, everything works fine.

Example:

<?
# $test="X";
setcookie("debug","1",time()+60*60*24*30,"","");
if ($test=="") {# test}
setcookie("debug","3",time()+60*60*24*30,"","");
?>
<HTML>
<HEAD>
<TITLE>w2k/PHP setcookie bug test</TITLE>
</HEAD>
<BODY>
BEGIN<BR>
<?
echo "Cookie: [".$_COOKIE["debug"]."] (HIT RELOAD)<BR>";
?>
END<BR>
</BODY>
</HTML>

When $test is not set, the cookie "debug" remains set to 1, while when
$test is set to any value (including "", an empty string), cookie will
be eventually properly set to 3.
