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

There is an an associative array in the variable $results. I can’t figure out how to loop through the $results array and

Here is the code challenge questions: The company you work for wants to send an email to its member base. They want the email to contain a complementary offer based on their membership level.

There is a send_offer function ready for you to use that accepts the following arguments: $member_id, $email, $fullname, $level.

The data from the database is currently in a PDOStatement object named $results. Loop through those results and pass them to the send_offer function.

I can’t figure out how to loop through the $results array and pass the $member_id, $email, $fullname, $level to the send_offer function.

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

/* 
 * helper.php contains
 * $results->query("SELECT member_id, email, fullname, level FROM members");
 */

It kinda defeats the purpose if i just post the code. There's no trick to it. get the associative array from the $results object (one of the fetch methods), use a foreach loop to iterate on each record with the function call for send in the foreach body. the parameters for the function call are just using array notation with the SQL fields as keys.

<?php
include "helper.php";

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

the contents of $results are iterable allowing use of the foreach loop directly. Otherwise, can use the foreach on the array you get back via fetchAll:

<?php
include "helper.php";
$rows = $results->fetchAll();
foreach($rows as $result){
 send_offer( $result['member_id'], $result['email'], $result['fullname'], $result['level']);
}

or use a for loop:

<?php
include "helper.php";
$rows = $results->fetchAll();
for($i = 0; $i < count($rows); $i++){  
 send_offer( $rows[$i]['member_id'], $rows[$i]['email'], $rows[$i]['fullname'], $rows[$i]['level']);
}

Thank you! Once I realized that I needed a foreach loop I was able to figure out the rest pretty quick.
