如何在YouTube视频标题中添加关键字

Question

我有一个YouTube模块，每天从一些YouTube用户帐户中删除视频。 我想知道，如何在YouTube视频标题中添加额外的关键字？

原标题：Jon Michael - 视频

我想将标题更改为 - Jon Michael - Video - Hot Clip

这是我用来将YouTube视频导入我网站的脚本模块。

的error_reporting（0）; $ feedURL ='http://gdata.youtube.com/feeds/api/users/'。$ username。'/ uploads？orderby =已发布＆amp; start-index = 1＆amp; max-results = 50';

$sxml = @simplexml_load_file($feedURL);
//print_r($sxml);
if($sxml)
    {
    // get summary counts from opensearch: namespace
    $counts = $sxml->children('http://a9.com/-/spec/opensearchrss/1.0/');

    echo "Total Videos=".$counts."<br/>";

    $_SESSION['total'] = ceil($counts->totalResults);
    $i='0';
    $_SESSION['page'] = 1;
    // iterate over entries in feed
    foreach ($sxml->entry as $entry) {

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

        // get video player URL
        $attrs = $media->group->player->attributes();
        $watch = $attrs['url']; 

        // get video thumbnail
        $attrs = $media->group->thumbnail[0]->attributes();
        $thumbnail = $attrs['url']; 

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

        // get <yt:stats> node for viewer statistics
        $yt = $entry->children('http://gdata.youtube.com/schemas/2007');
        $attrs = $yt->statistics->attributes();
        $viewCount = @$attrs['viewCount']; 

        // get <gd:rating> node for video ratings
        $gd = $entry->children('http://schemas.google.com/g/2005'); 
        if ($gd->rating) {
            $attrs = $gd->rating->attributes();
            $rating = $attrs['average']; 
        } else {
            $rating = 0;
