PHP Integrating PHP with Databases Querying the Database with PHP Working with Results

In the PHP section "integrating PHP with DataBases, in the challenge "Working with Results", Im not sure how to do this.

The TIP is... we used this method in the previous video. I went back through the past 2 videos several times and cannot figure out how to extract the data from $results in order to pass them through the function.

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
$x = send_offer($results($member_id), $results($email), $results($fullname), $results($level));

  1. You have to loop through the results.
  2. You have to use square brackets, not parentheses. Also, you have to use the column names instead of variables. E.g.:
$result['member_id']

not

$result($member_id)

Square brackets make sense, but I guess I don't understand the 'loop through the results' part.

e.g.:
