not sure

not sure how they want me to loop through the array generated by the fetchAll

index.php 
<?php
include "helper.php";
$results = $results-> fetchAll(PDO::FETCH_ASSOC);
var_dump($results);
for ($i = 0; $i < sizeof($results); $i++){
    foreach($results[$i] as $key => $notKey){
      send_offer($key);
    }
}
/* 
 * helper.php contains
 * $results->query("SELECT member_id, email, fullname, level FROM members");
 */

Once you get your results it should be a multi-dimensional array with the format as follows:

[0]=> array(4) {
    ["member_id"]=> string(1) "1"
    ["email"]=> string(23) "randy@teamtreehouse.com"
    ["fullname"]=> string(10) "Randy Hoyt"
    ["level"]=> string(6) "bronze"
}

After that iterating over it is up to you. I prefer foreach loops because there's one less operation to call (a count of the array to figure out where to stop). So for me the end result looks like:

foreach ($results as $result)
{
  send_offer($result['member_id'], $result['email'], $result['fullname'], $result['level']);
}
