Going on what mac_gyver said, which is spot on, First, you need to define the roles that your application will support. For example, you might have roles like admin, editor, and viewer. $roles = [ 'admin' => ['create', 'edit', 'delete', 'view'], 'editor' => ['edit', 'view'], 'viewer' => ['view'] ]; Next, you will need to assign these roles to your users. This can be done in your database. For simplicity, let's assume you have a user array that includes their role. $users = [ 'user1' => ['role' => 'admin'], 'user2' => ['role' => 'editor'], 'user3' => ['role' => 'viewer'] ]; Before allowing access to a specific page or functionality, you should check if the user has the required permissions based on their role. Here’s a simple function to check permissions: function hasPermission($userRole, $action) { global $roles; return in_array($action, $roles[$userRole]); } Now, you can use the hasPermission function to control access to different parts of your application. For example: session_start(); $currentUser = $_SESSION['user_id']; // Assume the user_id is stored in session $userRole = $users[$currentUser]['role']; if (hasPermission($userRole, 'edit')) { // Allow access to edit functionality echo "You have access to edit."; } else { // Deny access echo "Access denied. You do not have permission to edit."; } Hope this makes sense and may help you somewhat.
