SESSION problem

[Anon]

I'm using PHP and MySQL together.

I have several pages where the users can do different things with a certain MySQL database. In order to save some space I created an include file with a function that connects to the database.

<?
function db_conn()
{
mysql_connect("myhost","myuser","mypass") ;
mysql_select_db("mydb") ;
}
?>

On the target page (almost on each page) I have the following code to call this function:

<?
session_start() ;
require("includefile") ;
...
db_conn() ;
$query=...
...
?>

The code works but after accessing the second or third page I get the following error message on the screen:

Warning: Cannot send session cache limiter - headers already sent (output started at /home/davida/public_html/dolg_mod.php:7) in /home/davida/public_html/dolg_mod.php on line 8

How can I avoid this?

Any help is appreciated.

make sure you don't have any html/http output going to the browser before you call the session (even blank lines before the <? declaration will be counted as HTML white space)

Otherwise your heaer has been sent and the session can't utilize its cookies...

Is there a way to tell php not to send the header until u tell it to?
