In what order should a beginner approach developing a user authentication and data management system using PHP, MySQL, and HTML forms?

To develop a user authentication and data management system using PHP, MySQL, and HTML forms, a beginner should approach it in the following order: 1. Set up a MySQL database to store user information such as usernames, passwords, and other relevant data. 2. Create PHP scripts to handle user registration, login, and logout functionalities. 3. Use HTML forms to collect user input and interact with the PHP scripts to validate user credentials and manage user data. 

// Example PHP code for user registration
<?php
// Connect to MySQL database
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Process user registration form data
$username = $_POST['username'];
$password = $_POST['password'];

// Hash the password for security
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Insert user data into the database
$query = "INSERT INTO users (username, password) VALUES ('$username', '$hashed_password')";
$result = $mysqli->query($query);

if ($result) {
    echo "User registered successfully!";
} else {
    echo "Error: " . $mysqli->error;
}

// Close database connection
$mysqli->close();
?>
