<!-- This is the template file that's used as the "look and feel"
part of our 4 layer model demo (the "view" of the MVC model if you
like to think of it that way!). It's plain HTML / code the browser
with the addition of markers of the form %someword% which the PHP
program elements will replace by real dynamic server side content -->
<title>Example of a session based PHP application</title></head>
<h1>Data Entry - Page %current% of %phases%</h1>
Current operation: <b>%doing%</b><hr />
<h4>A little about this page</h4>
This is a sample application written in PHP for web use. A typical
web application requires the user to enter data on a series of forms
and presents results based on that series of forms. So a continuity
is required between the pages - data needs to be carried forward and
forms provided in context. But there will be a number of users on your
site at the same time, and only in exceptional circumstances (for
example with multiplayer games or with them bidding against each other)
should the data they are entering be shared.<br /><br />
PHP's sessions provide a built in tool for handling these requirements,
but even using this tool it is very easy to write a piece of logic that's
hard to maintain and includes a great deal of repetition. That's where
the "4 layer model" can come into play - and this page is a demonstration
of the 4 layer model in use.<br /><br />
