Yes Busy is correct. Here are some examples of what will and won't work:

Won't work 1:

<?php
 session_destroy(); /* Will be executed properly */ 
<html>
<head>
 header(\"Location: mypage.php\");  /* This will cause an error since we already started displaying the page! */ 
</head>
<body>
Hello, this will never be seen and therefore is not needed.
</body>
</html>
?>

Won't work 2:

<?php
header(\"Location: mypage.php\");  // This will redirect the browser properly.
session_destroy(); // This will never be executed!

<html>
<head>
</head>
<body>
Hello, this will never be seen and therefore is not needed.
</body>
</html>
?>

Will Work:

<?php
session_destroy(); // This will be executed properly before the redirect.
header(\"Location: mypage.php\");  // This will redirect the browser properly.

<html>
<head>
</head>
<body>
Hello, this will never be seen and therefore is not needed.
</body>
</html>
?>

So all you just need in your page is:

<?php
 session_destroy();
/* Any other php you want here as long as it doesn't output anything */
header(\"Location: mypage.php\");
?>

I hope those example give you an idea of the correct order of things.

You can use header redirect after logout, just has to be used before any output.
You can always destroy the session on the new page

Hi dk01,

Thanks for your suggestion! Unfortunately, I think this only solves the login problem (please correct me if I'm mistaken). In my logout page, I do some database cleanup code and that must occur before the redirect. So I guess that the

<?php
header(\"Location: ...\");
?>

.. function won't help? Is there anything else I can do?

A related question: Is meta refresh the only way to do redirects if there must be code before the redirect? Does anyone know of a better solution?

Thanks again!

It works on the server before a page is served and therefore allows for you to forget about what browser the user is using. Its proper use is:

<?php <php header(\"Location: URLHERE\"); ?>

You can only use this before any content has been sent to the browser otherwise you will get an error but it is a solid solution to your problem. Hope this helps some.

Just a correction on the above PHP code

<?php
 header(\"Location: URLHERE\");  
?>
