单击“查看更多”按钮显示保存在数组中的数据

Question

I am saving data in a array with max index 50. Now the problem is I am displaying only 10 results first. There is a button "view more". What I am trying to do is whenever I press view more it should display next 10 results from array and so on. All the data is saved in an array $data.

Here is the code:

    $lastindex=$_POST['ID'];
    $data =array();
    $file = file_get_contents('http://gdata.youtube.com/feeds /base/videos?max-results=50&lr=es&q=football&client=ytapi-youtube-search&v=2');

    $rss = new SimpleXMLElement($file);
    $limit = '50'; //Videos Limit to display
    $ctr = '0';
    $i=1;
    foreach($rss->entry as $idx => $key)
    {
        if($ctr == $limit)
        {
            break;
        }
        else
        {
            echo '<div>';
            $content = str_replace("watch?v=","v/", $key->content) ;
            $data[$i]=$content;
            $i++;
            echo '</div>';
            $ctr++;
       }
    }
