Loop through those results and pass them to the send offer function. I don't understand the send offer function.

Loop through those results and pass them to the send offer function. It states a hint that we used this method in last video but the only thing we changed in last video was:

$catalog = $results->fetchAll();

other then that I have all of the code written down. If anyone could help that would be amazing. Thank you.

index.php 
<?php
include "helper.php";

try {
    $results = $db->query(
        "SELECT member_id, email, fullname, level FROM members"
    );
} catch (Exception $e) {
    echo $e->getMessage();
}
//add code below this line
-->
$catalog = $results->fetchAll();
<--
?>

The send_offer function is a function inside the helper.php file that is included at the top of the file.

You would call the $results->fetchAll() method to get the results of the query, use a foreach to loop through the array, reference the values associatively and pass them to the function for each member in the array.

The code below should do the trick.

<?php
include "helper.php";

try {
    $results = $db->query(
        "SELECT member_id, email, fullname, level FROM members"
    );

    foreach ($results->fetchAll() as $result) {
        send_offer($result['member_id'], $result['email'], $result['fullname'], $result['level']);
    }
} catch (Exception $e) {
    echo $e->getMessage();
}
