Retrieve data from Database using CodeIgniter

In MySQL the SELECT statement is used to retrieve data from one or more tables:

Syntax:

SELECT column_name(s) FROM table_name

or

We can use the * character to retrieve ALL columns from a table:

SELECT * FROM table_name

Controller: 	User.php		application\controllers\User.php
Model:		User_model.php		application\models\User_model.php
View:		list.php		application\views\list.php

class User extends CI_Controller {

	public function __construct() {
		/*call CodeIgniter's default Constructor*/
		parent::__construct();

		/*load model*/
		$this->load->model('User_model');
	}
	
	public function list() {
		$data[‘result’]	= $this->user_model->list();
		$this->load->view(‘list’, $data);
	}
}

class User_model extends CI_Model {
	/*Select*/
	function list() {
		$this->db->select([“*”]);
		$this->db->from(‘user_info’);
		$query = $this->db->get();
		return $query->result();
	}
	
}
