Are there alternative methods in PHP to manage and control access to a website without solely relying on IP address blocking?

Instead of solely relying on IP address blocking to manage and control access to a website in PHP, you can implement user authentication and authorization. This involves creating a login system where users have to enter their credentials to access certain pages or functionalities on the website. By using sessions and database storage, you can track and manage user access levels effectively. 

session_start();

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

// Check user access level
$user_id = $_SESSION['user_id'];
$user_access_level = getUserAccessLevelFromDatabase($user_id);

if ($user_access_level < 2) {
    // Redirect user to unauthorized page
    header("Location: unauthorized.php");
    exit();
}

// Function to get user access level from database
function getUserAccessLevelFromDatabase($user_id) {
    // Query database to get user access level
    // Return user access level
}
