I have been messing around with the different Zend_Service components available in the framework, and in general am very pleased with the ease of use and functionality. However, Zend_Gdata seems somewhat complicated. Now I must admit that I have not spent much time with classes, and I am sure the structure is set up to accommodate the large amount of services that Google provides, but there is very little documentation and the API doesn't seem easily comprehensible, atleast compared to the Yahoo and Technorati APIs. It appears that Google staff wrote the code, and I guess that is why it breaks with the naming convention - i.e. all the other Services fall under Zend_Services_***, while Google's is Zend_Gdata. I am interested in the Youtube API, and it was easy to construct the query and get the result set back, but I found the result set to contain a lot of information (most of which was extraneous from my point of view), with many classes in it. Again, I was quickly trying to get it working and not at all interested in spending a lot of time learning the ins and outs of Google's API's. I am sure it will all click as I learn the other parts of Zend_Gdata, but for now, it is a pain. For example, using the code from the documentation, when you grab a result set and iterate through it, how do you grab the src for the flash movie? Digging through the code, I found it was $videoEntry->mediaGroup->content[0]->getUrl(). That's not to difficult, but then I noticed some of the results didn't have any data for $videoEntry->mediaGroup->content. Is that a fluke, or by design? What do the values in the content object mean? I can guess what isDefault means and most of them are obvious, but the comments in the code are completely worthless (well not completely, as it does tell me that the channels property of the MediaContent object is a integer...). What's the deal with the array of values - is the first value in the thumbnail array the preferable image, or just the first frame from the movie? I tried looking at the Google API docs, but that surprisingly didn't seem to shed much light either. I guess I should get off my ass, learn the API and contribute to the documentation. But its just so much easier to complain. Anyways, here is what I have quickly worked out. Once I start playing with the other Google services and have a better understanding of how all the classes fit together, I'll let you know... [php] $yt = new Zend_Gdata_YouTube(); $query = $yt->newVideoQuery(); $query->videoQuery = 'cat'; $query->startIndex = 10; $query->maxResults = 20; $query->orderBy = 'viewCount'; echo $query->queryUrl . "\n"; $videoFeed = $yt->getVideoFeed($query); foreach ($videoFeed as $videoEntry) { echo "---------VIDEO----------\n"; echo "Title: " . $videoEntry->mediaGroup->title->text . "\n"; echo "Description:" . $videoEntry->mediaGroup->description->text . "\n"; echo "Url to the Youtube page: " . $videoEntry->mediaGroup->player[0]->getUrl() . "\n"; echo "Thumbnail image of the video: " . $videoEntry->mediaGroup->thumbnail[0]->getUrl() . "\n"; if(!empty($videoEntry->mediaGroup->content[0])) { echo "Src to the video : " . $videoEntry->mediaGroup->content[0]->getUrl() . "\n"; } echo "\n\n\n"; } [/php]
