Re: [PHP] Problem grabbing value of session
I've decided to use the _SESSION method instead and it works just fine :)
So...thanks for suggesting that method, as it does look neater in the code
as well.

Re: [PHP] Problem grabbing value of session
I think the problem is one of scope.. though I have never tried starting a
session inside a function so I really don't know how it operates. But if
you do something like..
//
function is_valid($user, $privs)
{
// validate user..
if ($valid) {return TRUE;}
}
if (is_valid($user, $privs))
{
session_start();
session_register(user);
session_register(privs);
}
//
I don't know the answer to your question but this work with out a doubt as
it avoids any unkown problems with the scope of the session variables.

You can avoid the whole "session_register()" business if you simply
refer to these variables as $_SESSION['valid_user'] and
$_SESSION['privs'] -- after all, that's what they are, simply session
variables. By using this convention, you clarify exactly what kind of
variables they are each time you write them, which is good for
legibility later in the future. Also, you don't need to declare them as
global in your redirectinternal() function, since any $_* variable is
considered global at all times.

You'll have to post the context of this function (how it is called in
the script) for an answer to this question.
