Why can't I use session

Hi,

When I run this script:

<?php
session_start();
$_SESSION['test'] = "Session er smart";
echo $_SESSION['test'];
?>

I get this error-message:

Warning: session_start() [function.session-start]: Cannot send session
cookie - headers already sent by (output started at
/hotel/svp/WWW/html/php/auth.php:9) in /hotel/svp/WWW/html/php/auth.php on
line 10

Warning: session_start() [function.session-start]: Cannot send session cache
limiter - headers already sent (output started at
/hotel/svp/WWW/html/php/auth.php:9) in /hotel/svp/WWW/html/php/auth.php on
line 10
Session er smart


What is wrong?

As the error says: You are sending things before you do your sessionstuff.
Solution: don't. Put you sessionlogic on top of the page.

Actually you just need to make sure you call session_start() before
any output.

You can't send anything to the browser before starting your session, not even a
single blank line or space. Make sure your file starts like this:

-------------Start of file---------------------
<?PHP
session_start();
