How to get the totalResults entry from the YouTube video API

Question

I'm using PHP and the YouTube API to get videos from YouTube to feed to my web app, but I don't know how to get the totalResults entry

Here is my code:

$yt = new Zend_Gdata_YouTube();
$query = $yt->newVideoQuery();
$query->setQuery($searchTerm);
$query->setStartIndex($startIndex);
$query->setMaxResults($maxResults);
$feed = $yt->getVideoFeed($query);

echo $feed->totalResults; // this desn't work

Answer 1

The element itself is protected; you need to use the getTotalResults accessor:

echo $feed->getTotalResults();
