I am using following code to get title of some YouTube video, which was working fine previously but I am getting some error/warnings since last few days,

```
$entry = simplexml_load_file('http://gdata.youtube.com/feeds/api/videos/' . $key);
return ($entry) ? ucwords(strtolower($entry->children('http://search.yahoo.com/mrss/')->group->title)) : false;

```
