Help With Sessions

[Saeven]

Hi.

I'm trying to maintain an array of values across several pages using sessions.

At the header of my index.php I have the following code:

if( !isset( $SESSION['exists'] ) ){
echo "session did not exist";
session_name( GetHostByName( $REMOTE_ADDR ) );
session_start();
$SESSION['dcart'] = array();
$_SESSION['exists'] = 1;
}

Does that even make sense?

I have further down a few methods that are included from a seperate php file ( using include() ), that modify the array and that should print its contents. No deal however, it's like the array never gets played with.

I do know that session arrays should be accessed as $_SESSION['arrayname'][ index ];

Any hints/tips?
Thanks.

The $SESSION[] array is empty until you call session_start(). So $SESSION['exists'] is never set when you test it. So $SESSION['dcart'] and $SESSION['exists'] always get reinitialised.

I suspect

session_name(...);
session_start();
if(!isset($_SESSION['exists'])
{ $_SESSION['dcart']=array();
  $_SESSION['exists']=1;
}

is a bit closer to what you want.

If the page in which this header is included is re-accessed during the session, shall dcart be overwritten?
