I have the following code snippet:

if(in_array($name, $this->m_names))
{
$this->m_rules[$name][] = $rule;
return $_SESSION[$name];

}
In the entire script there does not appear to be any assignment to the
$_SESSION super global
so would it be fair to say that "return $_SESSION[$name];" not only
creates a session variable but returns it also? And what is it set
to?? It appears to me that $_SESSION[$name] = " " or possibly
something else. There is a bunch of $_SESSION[$somevariable]'s in the
code I'm looking at. The only reason I care is I would like to not
have to use any super globals at all but until I can figure out what
the original author was doing I'm stuck. I have successfully updated
his code (written in 2001) to work with php 5.3 but its not production
ready as register_globals has to be on and that's not a good thing. I
have googled and have seen no example of this type of use of $_SESSION
or $GLOBALS either.

If you need to see more code please email me directly

Thanks
