ShasScript: connect to MySqli using class

Today I want to show you guys how to connect to mysqli using class. You need to have 3 files.

config.php (your database connection)

fn.php (act as controller)

<?php
$db = DB_con::getInstance();
$mysqli = $db->getConnection();

class User{
  protected $db;
  public function __construct(){
   $this->db = new DB_con();
   $this->db = $this->db->ret_obj();
   
  }
   
public function check_login($username, $password) 
 {
  
  $password = md5($password);
  $ip=$_SERVER['REMOTE_ADDR'];
  $date_created = date('Y-m-d H:i:s');
       
        $query = "SELECT IdPengguna, Nama, Katanama, Katalaluan, Jawatan, Bahagian, KodThpCapai,KodFasiliti from Pengguna WHERE Katanama='$username' and Katalaluan = '$password'";
        $q = $this->db->query($query);
        $row_pengguna = $q->fetch_array();
        $totalrow_pengguna = $q->num_rows;
  
  
  if ($totalrow_pengguna >0 ){
   $_SESSION['log_stbp'] = true;
   $_SESSION['IdPengguna'] = $row_pengguna['IdPengguna'];
            $_SESSION['uname'] = $row_pengguna['Nama'];
   $_SESSION['ujawatan'] = $row_pengguna['Jawatan'];
   $_SESSION['ubahagian'] = $row_pengguna['Bahagian'];
   $_SESSION['ucapai'] = $row_pengguna['KodThpCapai'];
   $_SESSION['ufasi'] = $row_pengguna['KodFasiliti'];
         $_SESSION['log_kn'] = $row_pengguna['Katanama'];
   $_SESSION['log_kl'] = $row_pengguna['Katalaluan'];

return TRUE;
  }   
        else
  {
      return FALSE;
  }
    }
?>

index.php (this is where you files are)

<?php
session_start();
include_once 'config.php';
include_once 'fn.php';

$user = new User();
