Looping throughout each title

https://teamtreehouse.com/library/crud-operations-with-php/creating-records/reading-data

I'm have trouble finding how to show all the titles in the foreach loop and I'm hoping one of you will be able to help me

Thank you in advance.

index.php 
<?php
function get_podcasts() {
    include 'connection.php';

    //add code here
  try {

    return $db->query('SELECT * FROM podcasts');
    } catch (PDOException $e) {
        echo "Error! " . $e->getMessage() . "</br>";
        return array();
        }   

$podcasts = get_podcasts();
  $pod_array = $podcasts->fetchAll(PDO::FETCH_ASSOC);
  echo "<ul>"; foreach ($pod_array as $podcast) {
    echo "<li>".$podcast["title"]. " " . $podcast["website"]."</li>"; }
  echo "</ul>"; 
}

Hi, So first you prepare an sql query statement and you execute then you return the pdo object. Then we run the function and fetch all the results and do a foreach loop showing title and website. This is how I did it:

<?php
function get_podcasts() {
    include 'connection.php';

    //add code here
    $sth = $db->prepare("SELECT * FROM podcasts");
    $sth->execute();

    return $sth;
}

$podcasts = get_podcasts();
$results = $podcasts->fetchAll();
foreach($results as $result) {
  echo $result['title'] . ' - ' . $result['website'];
}
