How can session management be improved in PHP scripts to prevent login problems?

To improve session management in PHP scripts and prevent login problems, it is essential to regenerate the session ID after a successful login to mitigate session fixation attacks. This can be achieved by calling session_regenerate_id(true) after verifying the user's credentials during the login process. 

// Start the session
session_start();

// Perform user authentication
if($authenticated) {
    // Regenerate session ID
    session_regenerate_id(true);
    
    // Set session variables
    $_SESSION['user_id'] = $user_id;
    $_SESSION['username'] = $username;
    
    // Redirect to the dashboard
    header("Location: dashboard.php");
    exit();
} else {
    // Display login error message
    echo "Invalid credentials. Please try again.";
}
