What steps should be taken to create a secure and scalable CMS-like system using PHP for website content management?

To create a secure and scalable CMS-like system using PHP for website content management, you should implement user authentication and authorization, input validation to prevent SQL injection and XSS attacks, and proper data sanitization. Additionally, use prepared statements for database queries, implement role-based access control, and regularly update and patch your system to address any security vulnerabilities. 

// Example of user authentication using PHP sessions
session_start();

// Check if user is logged in
if(!isset($_SESSION['user_id'])) {
    // Redirect to login page
    header("Location: login.php");
    exit();
}

// Example of input validation to prevent SQL injection
$username = mysqli_real_escape_string($conn, $_POST['username']);
$password = mysqli_real_escape_string($conn, $_POST['password']);

// Example of prepared statement for database query
$stmt = $conn->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);
$stmt->execute();
$result = $stmt->get_result();
$user = $result->fetch_assoc();

// Example of role-based access control
if($user['role'] !== 'admin') {
    // Redirect to unauthorized page
    header("Location: unauthorized.php");
    exit();
}
