What are best practices for managing user sessions in PHP to prevent login issues?

To prevent login issues in PHP, it is important to properly manage user sessions. This includes setting session variables securely, validating user credentials, and implementing measures to prevent session hijacking or fixation. 

// Start the session
session_start();

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

// Validate user credentials
if ($valid_credentials) {
    // Redirect to the dashboard
    header('Location: dashboard.php');
    exit();
} else {
    // Display an error message
    echo "Invalid credentials. Please try again.";
}
