In PHP, why are my session variables persisted as references?

Question

Here\'s the code. It\'s a simple operation to check that a session ID isn\'t being spoofed by verifying the IP address:

session_start();
$session_ip_address = $_

If I have:

I get:

array(1) {
  ["blah"]=>
  string(4) "blah"
}

No references in sight. PHP 5.3.2 on Ubuntu 10.04.1
