            }, $row ) );
        }
        $paged++;
    } while ( count( $users ) === 500 );

    fclose( $out ); // phpcs:ignore WordPress.WP.AlternativeFunctions
    exit;
} );
```

## Notes

Protected by a nonce and the manage_network_users capability. Very large networks are exported in batches of 500 users to keep memory low.
