Sessions error

[fitzbean]

I'll start by saying everything works fine; as long as I put the @ in front of session_start(), it works fine.. it still works fine even if I don't, it just shows this unsightly error:

Warning: Cannot send session cache limiter - headers already sent (output started at /etc/etc/mdheader.php:1) in /etc/etc/mdheader.php on line 1

I have no clue why this is happening, but I can tell you the situation. I have many files within a website that use the same header and footer (mdheader.php and mdfooter.php), so instead of putting the session_start() in every file, I thought it would be ok just to throw in into the header file. The first line of every file that uses the mdheader.php is <? include('mdheader.php'); ?> Which then reads the first line of the header file which is <? session_start() ?>

Mind you, it does work, but not without error if I don't use @. Is it because I'm including the file first before calling session_start, even though the first thing the included file does is call it?

Thanks for any help

Supressing the error message doesn't make the error go away. You need to reorganize your code or remove whatever is causing the problem.

As soon as the Web server encounters anything that is textual -- including a blank space or a line ender -- it will output any pending HTTP response headers, followed by a blank line, which signifies the beginning of the message body.

At that point, you can no longer set headers, including cookies. The session function attempts to set a cookie.

You are seeing the error message because it is failing. It is failing because something has caused the server to begin transmitting the body of the document.

Hmm not sure if you understood what I meant by "everything works fine". Of course it would appear to work fine while supressing errors, but it actually does work. It maintains the registered variables etc. Perhaps you did realize that, but that was kind of why I found it abnormally strange.
