<
p>This tutorial is intended to introduce you to the CodeIgniter framework
and the basic principles of MVC architectureIt will show you how a
basic CodeIgniter application is constructed in step
-by-step fashion.</p>
<
p>In this tutorialyou will be creating a <strong>basic news application</strong>. You
will begin by writing the code that can load 
static pagesNextyou
will create a news section that reads news items from a database
.
Finally, 
you&#8217;ll add a form to create news items in the database.</p>
<p>This tutorial will primarily focus on:</p>
<
ul class="simple">
<
li>Model-View-Controller basics</li>
<
li>Routing basics</li>
<
li>Form validation</li>
<
li>Performing basic database queries using &#8220;Query Builder&#8221;</li>
</ul>
<
p>The entire tutorial is split up over several pageseach explaining a
small part of the functionality of the CodeIgniter framework
You&#8217;ll go
through the following pages:</p>
<

and will be doing some basic database operations.</li>
