2. Create the database Use the following SQL to create the login_system database and users table:

CREATE DATABASE login_system CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

USE login_system;

CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    email VARCHAR(255) NOT NULL UNIQUE,
    password VARCHAR(255) NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

3. Update database credentials Edit db.php and set your local MySQL credentials:

$host = 'localhost';
$db   = 'login_system';
$user = 'root';
$pass = ''; // Change if needed

4. Run the project Open index.php in your local server (e.g., http://localhost/php-login-bootstrap/index.php)
