What strategies can be used to display only the links that a user has access to on the index.php page in a PHP web application?

To display only the links that a user has access to on the index.php page in a PHP web application, you can implement a role-based access control system. This involves assigning roles to users and then checking the user's role before displaying certain links. By doing so, you can ensure that users only see links that are relevant to their role.

// Check the user's role before displaying links
if($userRole == 'admin'){
    echo '<a href="admin.php">Admin Panel</a>';
}
if($userRole == 'user'){
    echo '<a href="profile.php">Profile</a>';
}
