Re: [PHP] Session problem

[Pete James]

You need to start the session at the beginning of the script, or use 
output buffering.

Either:
<?php
session_start();
require("...
...
or

<?php
ob_start();
require("...
...
You're trying to output stuff to the screen (which implicitly sends the 
headers) then trying to send more headers by calling session_register() 
(which implicitly calls session_start() )

HTH.
