For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

<!-- 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
will understand (so you can add in style sheets, Javascript, etc)
with the addition of markers of the form %someword% which the PHP
program elements will replace by real dynamic server side content -->

<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 />
