Do you have session_start() at the top of your page before anything else?

As Ryan alluded to, it's just another case of text being outputted -- even a blank space, before the cookie function is called.

If it still doesn't work then just make sure that the session is being started before ANY html output.

Take a look at PHP: session_start - Manual?

or you could use ob_start() ?

PHP Code:


		
			

echo 'wadwadwa';

session_start();

$_SESSION['ls'] = 'dawdwa';

produces the error because the text has been sent to the client, so use output buffering to pipe all the text/cookies/session cookies all at once

PHP Code:


		
			
ob_start();
echo 'wadwadwa';

session_start();

$_SESSION['ls'] = 'dawdwa';
ob_flush();

it could also be being caused by whitespace before the <?php.
