This question already has an answer here:

• PHP SimpleXML Namespace Problem 1 answer

There is an example how to search videos by search term in the documentation, but how to extract information from single video when you have the videoID.

<?php

  // set feed URL
    $feedURL = 'http://gdata.youtube.com/feeds/api/videos/LjhCEhWiKXk?v=2';

    // read feed into SimpleXML object
    $sxml = simplexml_load_file($feedURL);


// this get the video title
$videoTitle = $sxml->title;


?>

I get only the video title ... also there is no views count,description and duration.

</div>

You have to completely parse video entry ($sxml) to get more information:

Children nodes of Entry $sxml:

// get nodes in media: namespace for media information
$media = $entry->children('http://search.yahoo.com/mrss/');

Get duration: ($media->children ...)

** Element yt:duration under the media:group element stores the length of the video, in seconds**

// get <yt:duration> node for video length
$yt = $media->children('http://gdata.youtube.com/schemas/2007');
$attrs = $yt->duration->attributes();
$obj->length = $attrs['seconds'];
