Thank you, I think this is the cleanest way to access session variables
from within a function.

Use the superglobal array, $_SESSION, to access session variables directly.

for example:

function do_login($username, $password)
{
   // check username and password here

   if($valid_login)
   {
      $_SESSION['logged_in'] = true;
   }
}
