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.

Try the following code:

<?
# $test="X";
setcookie("debug","1",time()+60*60*24*30,"","");
if ($test=="") {setcookie("debug","2",time()+60*60*24*30,"","");}
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.

There's really no bug here. You're getting a notice about unitialized variable which causes the rest of the headers not to get send. Try adding 'error_reporting(0);' in the beginning of your script..

I've restored the old php.ini from the previous PHP 4.2.1 installation and the script works fine.

Not a PHP bug, after all, but a configuration issue.
However, since the problem arose I think it deserved to be discussed and solved, even as a "bogus" bug.

Since PHP returns a notice when an unset variable is invoked, E_NOTICE should be disabled from error_reporting to make scripts work in given conditions:

error_reporting = E_ALL & ~E_NOTICE

Note that since PHP v4.2.2 (?)
error_reporting = E_ALL
is the default

no it is not.
The default in E_ALL ~E_NOTICE (see php.ini-dist).

If you use php.ini-recommended, than the default is E_ALL, but also, the default is display_errors Off.

Whichever way you look at it, it is a configuration error envoked by changing something to a non-default.

There's really no justification for the errors in your ways :)
