< p > This tutorial is intended to introduce you to the CodeIgniter4 framework
2018-09-23 09:21:22 -07:00
and the basic principles of MVC architecture. It will show you how a
2019-03-09 09:37:12 -08:00
basic CodeIgniter application is constructed in a step-by-step fashion.< / p >
2019-01-30 07:49:33 -08:00
< p > If you are not familiar with PHP, we recommend that you check out

< p > In this tutorial, you will be creating a < strong > basic news application< / strong > . You
will begin by writing the code that can load static pages. Next, you
will create a news section that reads news items from a database.
Finally, you’ 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 >
