Change Menu for People that are logged in

Question

I have a header made for people that are logged in, showing their name, the logout option, as well as the usual things such as home, profile, search, etc.
But I also made a header for the people that are not logged in. It shows only the logo as well as the form to flll in email and password.
I would like to make it in php so that when someone comes to the site or signs in it checks
If the user is logged in
show header_logged_in
show content
show footer
If the user is not logged in
show header_visitor
do not show content (instead I have a page that tells the visitor to sign in or sign up)
show footer
But I'm not sure how I would code this to where it knows whether or not they are logged in, and how to keep the content hidden from those who have not yet.
Any help would be really appreciated. Thanks ahead of time.

Hi Mike,
Without knowing more about how users login and out I can only give you an example of how it's done.
This uses a session variable check then includes
<?php
session_start();
if ( isset ($_SESSION ['$login_status']) ) {
          include 'header_logged_in.php';
} else {
          include 'header_visitor.php';
?>
It's a basic example but there you have it.
If you give some more details a more accurate answer can be given.
Hope that helps anyway.
