How to check checboxes in a php table?

So I have a guestlist in a PHP table, but I want to check the guests that have arrived.

$sql='SELECT * FROM guestlist LIMIT ' . $this_page_first_result . ',' .  $results_per_page;

$result = mysqli_query($connect, $sql);

echo "IDNameSurnameCheck-in"; while($row = mysqli_fetch_array($result)) { echo "" . $row["id"]. "" . $row["name"]. " " . $row["surname"]. "";

} echo "";
