Once again - I was wrong in my suggestion as Ashley has pointed out so 
correctly.  Had to test it out this morning only to discover that I had 
never done quite that kind of Header redirect before.

So - the include method still works, as would the single script 
'controller' method.  Within a php script any file is accessible (within 
your domain at least) and may therefore be included and executed.  On 
the other hand, if you must have the target script in your 
web-accessible tree, simply establish some kind of security handler and 
add logic to your page(s) to check permissions before displaying 
anything.  This handler could be based upon session vars, cookies, db 
entries (my pref).  Once established it can be a universal addition to 
any and all of your appls.

My personal method is to create a db table containing an appl name, page 
name, and a non-unique security level (I use an integer).  Then have an 
admin screen for creating userids for an appl with multiple recs each 
containing a security level for that user for that appl. Then have a 
signon method that validates credentials and builds a session array 
containing all the user's security levels.  In every page that I want 
secured, I call a function with that script's internal pagename and appl 
name and confirm that the page's sec level is contained in the user's 
session array.  I also have a master level (99) that if present gives 
global access for myself as administrator.  There's a bit more to it, 
but that's my security method.
