Are classes always references when assigning them to new variables? Or are copies of the class made? I'd assume the former.

For example:

$HTTP_SESSION_VARS['user'] = new User();

Later in a function foo() which assign statement should I use? And does it matter?

$user = $HTTP_SESSION_VARS['user'];

or

$user = &$HTTP_SESSION_VARS['user'];

TIA.
