Session redirect in php and asp

These are examples of correct ways to handle access and redirects in sessions in asp(1.0|vbs) & php.. I dont know how may times I see this done wrong..

ASP example

If NOT Session("Authenticated") = 1 Then
Response.Redirect ("login.asp")
'Response.Redirect ("login.asp", true); '<= This is the same as the default
'Exit ' <= This is called with default True statemens as above
End If

PHP Example
if ($_SESSION['access'] != "yes")
{ header(Location:login.php); /* Redirect browser */
exit; /* Make sure that code below does not get executed when we redirect. */
//Code Following Should not be executed unless authenticated.
echo ("secure code");

Note: Since PHP 4.4.2 and PHP 5.1.2 this function prevents more than one header
to be sent at once as a protection against header injection attacks.

What if $_SESSION['access'] is null? or not set? or is this an assumption?

test it and see.. that's the most appropriate way.
