STEP 1 : INSTALL FRAMEWORK
The first step you must first download the file Codeigniter on its official web page, Here
Extract the CodeIgniter.rar file you have downloaded into your web server's root directory, for example for example C:\ Xampp\Htdocs\CodeIgniter (for those using Xampp web server). Then go into application folder. Inside this application folder you will often change later and in the next model
Run Xampp Control Panel then enable it on Apache and MySQL module. And if you try to run on a web browser then the page will appear as below.
STEP 2 : CONFIGURE CODEIGNITER
Open the config.php by using text editor like Sublime, file located in the C:\xampp\htdocs\CodeIgniter\application\config\config.php, which is useful to begin configuring the CodeIgniter framework.
Change the clean and dynamic url base on CodeIgniter, customize it to the location where your CodeIgniter folder resides on C:\Xampp\Htdocs.
For example: Your CI folder is in www / ci folder then change line
Because in this tutorial we will build CI in our local server. Localhost is the name for the local server that is on our computer, and basically the computer is the server, and the server is the computer.
Then the next stage is setting up the database. Open the database.php file with applications like Sublime, Notepad++ and others, database.php configuration file located in application/config/ database.php
Change hostname, username, password, and database name (later we will create a database, to temporarily make its name first) then adjust to your mysql settings. As an example :
