[UPHPU] php user authentication

[michael geary]

a header() redirect must be called before anything is *output* to the  
browser. If you have output_buffering turned on, this is relaxed for  
the most part, but there are good reasons to avoid that sloppiness and  
separate your app and display logics such that you can do a header()  
redirect any time in your app logic, which is finished before your  
display logic is reached. Just make sure you do an "exit" after a  
header redirect, or the rest of the code on that page WILL be executed  
before the redirect happens.
