I wish this help you You have to create a new JSONObject for each resultset. Create one in the loop, and add it to the array. Otherwise, you're just replacing the fields for the old object, and adding another reference to it to the results.

I hope this helps you . First off, if $code thats is going to be used in code is VARCHAR/TEXT, you should have wrapped it with quotes.
But since you're preparing, just bind it:
$token = "callumc";

// add a named placeholder for preparation
$query = "
    FROM signup
        code = :code

try {
    $stmt = $db2->prepare($query);
    // bind it
    $stmt->execute(array(':code' => $token));
} catch (PDOException $ex) {
    die("Failed to run query: " . $ex->getMessage());
$results = $stmt->fetch(PDO::FETCH_ASSOC);
echo $results['username']; // and others
