How can a PHP developer ensure that only non-admin users are displayed in a rankings system?

To ensure that only non-admin users are displayed in a rankings system, a PHP developer can check the user role before displaying them in the rankings. This can be achieved by retrieving the user role from the database or session and only displaying users with a role other than admin. 

// Assuming $users is an array of user data with 'role' field indicating user role

foreach ($users as $user) {
    if ($user['role'] !== 'admin') {
        echo $user['username'] . ' - Rank: ' . $user['rank'] . '<br>';
    }
}
