Re: Header Processing

Hi Tom,

I was looking at an application with the following code snippet:

ob_start();
session_name('foo');
session_start();
if (!$_SESSION['bar']) { header("Location: http://"; . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . "/index.php");
ob_end_clean();
exit();
}

I am under the impression that the "header" redirection is immediate.

That is wrong.
This is not like, for example ASP/VB's Response.Redirect.
header() function in PHP does excact what it says and nothing more: Setting a header.

Am I correct or will the 'ob_end_clean()' and 'exit()' actually
process.

They will be processed.

Bottomline: If you need a 'redirect' via header("Location...") always call exit after that, or the script will merely run on untill it ends.
