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.

Re: session_start(): Cannot send session cookie - headers already sent by

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.

Re: session_start(): Cannot send session cookie - headers already sent by

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.

Re: session_start(): Cannot send session cookie - headers already sent by

Sometimes the problem is caused by the Dreamweaver's "Include Unicode Signature (BOM)" property.
To turn it off go to Modify > Page Properties > Title/Encoding in Dreamweaver and uncheck "Include Unicode Signature (BOM)"

I am happy

I had the same problem and solved it. do you know how? use error suppression operator @ symbol just before session_start().
i. e., <?php
ob_start();
@session_start();
?>
It really works without any problem :-)

Re: session_start(): Cannot send session cookie - headers already sent by

If your going to use the ob_start() tag dont forget the ob_flush() tag right at the end of the page.
But obviously its better if you can actually sort the problem out.
