Using Zend_Gdata_Spreadsheets for public spreadsheets?

Question

I have this code that works to download a Google spreadsheet and load some data from it. If the published table is publicly available, how can I change the code so as not to require a username / password?

$key="keytothespreadsheet";
$user="[e-mail]";
$pass="*****";

$authService = Zend_Gdata_Spreadsheets::AUTH_SERVICE_NAME;
$httpClient = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $authService);
$gdClient = new Zend_Gdata_Spreadsheets($httpClient);
$query = new Zend_Gdata_Spreadsheets_DocumentQuery();
$query->setSpreadsheetKey($key);
$feed = $gdClient->getWorksheetFeed($query);
print_r($feed);

Answer 1

In the following line, an HTTP client is optional:

$gdClient = new Zend_Gdata_Spreadsheets($httpClient);

So, just don't pass by. The following equivalents:

$gdClient = new Zend_Gdata_Spreadsheets();
// or
$gdClient = new Zend_Gdata_Spreadsheets(null);
// or
$gdClient = new Zend_Gdata_Spreadsheets(new Zend_Http_Client());

    $spreadsheetService = new Zend_Gdata_Spreadsheets(null);
    $query = new Zend_Gdata_Spreadsheets_CellQuery();
    $query->setSpreadsheetKey($spreadsheetKey);
    $query->setWorksheetId($worksheetId);
    $query->setVisibility('public'); //options are 'private' or 'public'
    $query->setProjection('basic'); //options are 'full' or 'basic'
    $cellFeed = $spreadsheetService->getCellFeed($query);

    foreach ($cellFeed as $cellEntry) {
        $text = $cellEntry->content->text;
        //Do something
        break; //I only wanted the first cell (R1C1).
    }
