Zend Framework gives you the possibility to interact with Gdata services, which are provided by most of the Goolge services. You can find more on the docs page of Zend_Gdata. The basic principle is that you can connect a service with you API key, given by Google. What I’m about to show you is how do connect such a service.

In theory Zend_Gdata depends on Zend_Http_Client and you’ve to connect it with an instance of this class.

// 1. setup API key
$apiKey = 'your_api_key_here';

// 2. retrieve videos via GData Atom
$client = new Zend_Http_Client();
$gdata = new Zend_Gdata_YouTube(null, 'my-app', null, $apiKey);

Note that you’ve to replace your API key in the chunk above.

Now once that you’ve connected the YouTube service you can iterate through the entries from the video feed.

$videoFeed = $gdata->getUserUploads('username');
foreach ($videoFeed as $entry) {
    echo $entry->getTitle();
}

The thing is that you can modify a bit the code above. As ZF docs says if you don’t setup a Zend_Http_Client a default with default configuration, so you can omit this and simple write:

// 1. setup API key
$apiKey = 'your_api_key_here';

// 2. retrieve videos via GData Atom
$gdata = new Zend_Gdata_YouTube(null, 'my-app', null, $apiKey);
