Weird PHP warning while session_start()


with the simpliest php page

PHP Code:
(); // start up your PHP session!
I have the following warning:
Warning: s in /home/Web-home/htdocs/ps.php on line 2 Call Stack: 0.0002 66640 
1. {main}() /home/Web-home/htdocs/ps.php:0 0.0003 66640 
2. session_start() /home/Web-home/htdocs/ps.php:2 
Dump $_SERVER $_SERVER['REQUEST_METHOD'] = 'GET' $_SERVER['REQUEST_URI'] = '/ps.php' $_SERVER['HTTP_USER_AGENT'] = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/20100722 Toolbar 2.0 Firefox/3.6.8' Dump $_REQUEST $_REQUEST['PHPSESSID'] = '3vcd5c3km29i6ddiagrs68ligv8u0m77' 
Warning: U in Unknown on line 0 Warning: U in Unknown on line 0
What could be the problem? Something is with PHP/Apache setup?

PHP Version 5.2.5
IHS (Apache 2) + ldap
Session Support enabled

From what I can see of this cookie method, it's incredibly vulnerable to encoding errors and can have issues interacting with certain file systems. I would advise taking a look at the php manual page for this, a lot of people have had various errors, yours maybe related to one of theirs and the solution the same.
