I suggest you read the other threads you started, as well as the manual. There are also some very good how-tos out there to teach you how to properly do what you want to.

Check the manual... if that script is included check that the file that it is actually including it doesn't have any print or echo. session_start() should be at the very beginning of the code.

Also change this:

[php]
<?session_start();?>
<?php
include"db_config.php";
[/php]

to this

[php]
<?php
session_start();
include"db_config.php";
[/php]

There is no need to break the PHP tags there... and use <?php also instead of <? it will make the script work in other servers. Or maybe your server doesn;t support short php tags.

I'm assuming that your including this file into another file, and in that other file you have already echoed something when this file is included.

Otherwise I cannot see what is wrong, as suggested the manual always helps.
