  • 0

I have the classical Symphony flash message implementation:

$_SESSION['flash'] = "This is a flash message";
header('location: index.php');

It works fine on two different servers but has a strange behavior on a third one, a hosted server, LAMP stack, of which configuration I’m not aware about in detail.
On the third server the script execution brings up first a warning – that the headers have already been sent … (but I didn’t output anything, on the other servers it works) – then if I trigger again the redirecting event, a hyperlink, it brings me into the index.php file with the message rendered. I know how to make it “portable”, by using JavaScript to redirect, but I wonder what is the cause of this behavior. I suspect a server configuration for a PHP or Apache module.
Thanks for your hand!

    Javascript is not the portable solution,
    but the least portable solution.

    The unknown output could be caused by some white-spaces like BOM.
    Or you can take a look on headers_sent
