What are the potential security risks of using the same login system for users with different roles in a PHP application?

Using the same login system for users with different roles in a PHP application can pose security risks as it may allow users to access functionalities or data that they are not authorized to. To mitigate this risk, it is important to implement role-based access control (RBAC) where users are assigned specific roles and permissions. This way, each user will only have access to the functionalities that are appropriate for their role. 

// Implementing role-based access control (RBAC)
session_start();

// Define roles and permissions
$roles = [
    'admin' => ['dashboard', 'manage_users'],
    'editor' => ['dashboard', 'edit_content'],
    'user' => ['dashboard']
];

// Check user role and redirect based on permissions
function checkRole($role, $permission) {
    if (isset($_SESSION['role']) && in_array($permission, $roles[$_SESSION['role']])) {
        return true;
    } else {
        header('Location: unauthorized.php');
        exit();
    }
}

// Example usage
if (checkRole('admin', 'manage_users')) {
    // Allow access to manage_users functionality
} else {
    // Redirect to unauthorized page
}
