want to call particular youtube video analytics

[Narendra Sharma]

so far i have done the code but didn't get any success on the code.

$YoutubeChannelId=$snippet['items']['0']['snippet']['channelId'];

$optparam = array('video==**7Gg5yn44A;country==IN');

$metrics='views,comments,favoritesAdded,favoritesRemoved,likes,dislikes,shares,estimatedMinutesWatched,averageViewDuration,averageViewPercentage,annotationClickThroughRate,annotationCloseRate,subscribersGained,subscribersLost'; 

$YoutubeChannelReports=$youtubeAnalytics->reports->query("channel==$YoutubeChannelId", "2012-08-14", "2013-09-20", $metrics,$optparam);

echo "<pre>";print_r($YoutubeChannelReports);echo "</pre>";
