How can PHP sessions be effectively utilized to enhance the security of a web application like the one described in the forum thread?

Issue: PHP sessions can be effectively utilized to enhance the security of a web application by storing sensitive user data on the server-side and generating unique session IDs to prevent session hijacking. Code snippet: 

// Start a session
session_start();

// Set session variables
$_SESSION['username'] = 'example_user';
$_SESSION['user_id'] = 12345;

// Validate session data on each page
if (!isset($_SESSION['username']) || !isset($_SESSION['user_id'])) {
    // Redirect to login page or display an error message
    header("Location: login.php");
    exit();
}
