How can the separation of access credentials for admin users be implemented securely in a PHP application?

To securely implement the separation of access credentials for admin users in a PHP application, you can use role-based access control (RBAC) where each user is assigned a specific role (e.g., admin or regular user) and only users with the admin role have access to certain functionalities or pages. 

// Example implementation of RBAC in PHP

// Define roles
define('ROLE_ADMIN', 1);
define('ROLE_USER', 2);

// Check user role before granting access
function checkUserRole($role) {
    if ($role !== ROLE_ADMIN) {
        // Redirect to unauthorized page or show error message
        header('Location: unauthorized.php');
        exit;
    }
}

// Example usage
$userRole = ROLE_ADMIN; // This should be fetched from the user data
checkUserRole($userRole);

// Admin-only functionality
echo "Welcome, Admin!";
