I have built a login application in PHP(no frameworks) with MySQL as Database.
I am getting warnings and errors when I attempt to run index.php on localhost (WAMP). The error says:
"Warning: require_once(Cl_User.php): failed to open stream: No such file or directory in C:\wamp\www\login\config.php on line 18"
"Error: Fatal error: require_once(): Failed opening required 'Cl_User.php' (include_path='.;C:\php\pear') in C:\wamp\www\login\config.php on line 18"
What should I do to remove errors?
Here is the php file codes:
a. index.php:
ob_start();
session_start();
require_once 'config.php';
// Initialize User Class
$user_obj = new Cl_User();
?>
if( !empty($_POST)) {
try {
$data = $user_obj->login( $_POST );
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in']){
header('Location: home.php');
}
} catch (Exception $e) {
$error = $e->getMessage();
}
}
if(isset($_SESSION['logged_in']) && $_SESSION['logged_in']){
header('Location: home.php');
}
?>

e. DBclass.php:
class Cl_DBclass
{
public $con;
public function __construct()
{
$this->con = mysqli_connect(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME);
if( mysqli_connect_error()) echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
}
?>
What I have tried:
I don't know much about PHP(like autoload function in PHP). I need a solution to this problem because I have to make the application further by adding other useful features.
