PDO response to json

Im new to PHP and trying to make a very simple api (good way too learn i think), why doesnt this work? When loading this page the output is: {"queryString":"SELECT id, Name FROM Food WHERE userID=1 ORDER BY Name"} and not the JSON-string that I want

$dbh = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password);

$response = $dbh->query("SELECT id, Name FROM Food WHERE userID=1 ORDER BY Name");

$responseJSON = json_encode($response);

header('Content-type: application/json');
echo "$responseJSON";

$dbh = null;

Nothing is wrong with the query because i get what i want when trying this:

$dbh = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password);

$response = $dbh->query("SELECT id, Name FROM Food WHERE userID=1 ORDER BY Name");

    foreach ($response as $row)
        {
            print $row['Name'] . ' ';
        }


$dbh = null;

outputs: Bacon Cheese chips

$dbh->query retuns a PDOStatement object, not the rows. To add the rows to the json, call fetchAll on the object.

$response = $dbh->query("SELECT id, Name FROM Food WHERE userID=1 ORDER BY Name")->fetchAll();

You may also specify the fetch mode, e.g.

fetchAll(PDO::FETCH_ASSOC);
