Hello Friends,

If you are looking to install in Codelgniter. Please review the below process:

Step 1 :: Download Codelgniter from "https://www.codeigniter.com/download"

Step 2 :: Unzip this folder and place this on root folder

Step 3 :: Rename this folder with your project name like I have rename this "mytutorial"

Step 4 :: Now open "mytutorial/application/config/database.php" and set your

               database detail here

$db['default'] = array(
	'dsn'	=> '',
	'hostname' => 'localhost',    
	'username' => 'root',       // CHANGE THE WITH YOUR DATABASE USERNAME
	'password' => 'admin',      // CHANGE THE WITH YOUR DATABASE PASSWORD 
	'database' => 'mytutorail', // CHANGE THE WITH YOUR DATABASE NAME
	'dbdriver' => 'mysqli',
	'dbprefix' => '',
	'pconnect' => FALSE,
	'db_debug' => (ENVIRONMENT !== 'production'),
	'cache_on' => FALSE,
	'cachedir' => '',
	'char_set' => 'utf8',
	'dbcollat' => 'utf8_general_ci',
	'swap_pre' => '',
	'encrypt' => FALSE,
	'compress' => FALSE,
	'stricton' => FALSE,
	'failover' => array(),
	'save_queries' => TRUE
);

Step 5 :: Now you can run your project on browser like my URL is "http://localhost/mytutorial"

Currently this is calling from the "mytutorial/application/controllers/Welcome.php" as default controller. Now you can define your controller, model and view files and enjoy the Codelgniter. Suppose I have created a Controller named "Users.php" with it's model and view files. Now I can run my user controller  as "http://localhost/mytutorial/index.php/User"
