Well, I'm not sure how your ViewHelper could possibly screw things up,
but the $_SESSION variable is already thread-safe, unless you've
hacked up a custom session handler that isn't thread-safe... In which
case you've got bigger problems than just this one function. :-v
$_SESSION gets a lock on the session data file at session_start which
is not released until session_*close
So instead off all that OOP stuff, if you just did:
if (isset($_SESSION['is_logged_in'])){
}
and used unset($_SESSION['is_logged_in']) to log somebody out, well,
you'd pretty much have the same functionality in a lot less lines of
code...
But, hey, I'm sure the ViewHelper has a lot of other Added Value, right?
