how can I append querystring to object? - php

Question

Google has chanced some things with their calendar API, and now I need to fix some strange symbols that are adding themselves to text. I found this thread which exactly describes the issue I'm dealing with:
http://www.google.com/support/forum/p/Calendar/thread?tid=25ac3d762b235a51&hl=en
The solution is to append "&hl=en" or "?hl=en" to the end of my 'basic' URL feed.
I'm confunsed how to do that though, because I am retrieving the feed as an object with Zend_Gdata:
<?php
// load library
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata');
Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
Zend_Loader::loadClass('Zend_Gdata_Calendar');
Zend_Loader::loadClass('Zend_Http_Client');
// create authenticated HTTP client for Calendar service
$gcal = Zend_Gdata_Calendar::AUTH_SERVICE_NAME;
$user = "xxxxx";
$pass = "xxxxx";
$client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $gcal);
$gcal = new Zend_Gdata_Calendar($client);
$query = $gcal->newEventQuery();
$query->setUser('xxxxx#group.calendar.google.com');
$secondary=true;
$query->setVisibility('private');
$query->setProjection('basic');
$query->setOrderby('starttime');
$query->setSortOrder('ascending');
//$query->setFutureevents('true');
$startDate=date('Y-m-d h:i:s');
$endDate="2015-12-31";
$query->setStartMin($startDate);
$query->setStartMax($endDate);
$query->setMaxResults(30);
try {
$feed = $gcal->getCalendarEventFeed($query);
} catch (Zend_Gdata_App_Exception $e) {
echo "Error: " . $e->getResponse();
}
?>
I tried to do this with no luck:
$query->setProjection('basic?hl=en');

Note: I've not used any of this before so I apologize if this doesn't work :)
The documentation says that getCalendarEventFeed() can take a URL as the parameter.
So we can change this...
$feed = $gcal->getCalendarEventFeed($query);
... to this in order to add the parameter to the query string:
$eventUrl = $query->getQueryUrl() . '?hl=en';
$feed = $gcal->getCalendarEventFeed($eventUrl);
Obviously, this is a simplified example - you should still perform the following two checks:
Make sure $query is an instance of Zend_Gdata_Query before calling getQueryUrl() on it.
Ensure that there are no other query parameters already added to $eventUrl so that we can use &hl=en rather than ?hl=en. You could probably use Zend_Uri for this.
