How to retrieve items from database using JSONArray

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.
while(rs.next()){
    //new line:
    JSONObject Obj = new JSONObject();
    // original part looks fine:
    Obj.put("uname",rs.getString("uname").trim());
    Obj.put("comment",rs.getString("comments").trim());
    CommArray.add(Obj);
}

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 = "
    SELECT
        id,
        code,
        username
    FROM signup
    WHERE
        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
