I have tested the "baking" file (please see below) in two machines and received the same error:

Warning: Cannot add header information - headers already sent by (output started at ...\setcookie.php:1) in ...\setcookie.php on line 2

The first system used: WinXP Pro., IIS (built-in with WinXP).

The second system used: FreeBSD 4.6, Apache/1.3.26.


The "baking" file's content:
<?php
setcookie ("Chip_Name",$Chip);
echo "<BODY OnLoad=\" location='".$forwarding."' \">";
?>

The test file's content:
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<?php
echo $Chip_Name;
?>
<a href="setcookie.php?Chip=Chocolate&forwarding=<?php echo $PHP_SELF ?>">Test SetCookie() Function</a>
</body>
</html>

Is it a bug?!? Or there is something wrong with my code?!? I couldn't even "bake" any cookie because some headers were sent first, but how could?

Sorry, but the bug system is not the appropriate forum for asking
support questions. Your problem does not imply a bug in PHP itself.
For a list of more appropriate places to ask for help using PHP,
please visit http://www.php.net/support.php

Thank you for your interest in PHP.

My code has nothing wrong (as you can see)! This was a bug and I reported it. However, I guess I should have done it with an aggresive tone to get more attention from you.

Cheer

It is very very unlikely that there is a PHP bug here.  You probably have something before the opening <?php tag in the file that sets the cookie.  Put up a .phps or a .zip file somewhere with the actual files in question so we can have a look.  And when we do explain your mistake to you, you can apologize nicely to sniper.

Thanks rasmus,

Below are the links:

Test file:
http://vietecon.com/php/Test_Cookie.php

SetCookie file:
http://vietecon.com/php/setcookie.php

Source codes in ZIP
http://vietecon.com/php/cookie.zip

Domain vietecon running FreeBSD 4.6, Apache/1.3.26 (as I described).

P.S. Sorry to sniper if my tone was harsh to you.

And "od -c" of your setcookie.php file reveals, as I predicted, that you have crap before your <?php tag.

Use a non-bogus text editor and it should work fine.

Thank you!!!

BTW, attention to anyone who uses Dreamweaver MX to encode your document in Unicode (utf-8). You will experience the same problem. I changed the encoding to Western (Latin1) and it worked just fine.

I guess the 'crap' you have mentioned is some code reporting that the document was encode in Unicode (utf-8).
