几个链接我在PHP做的是这个whorks罚款的链接，我可以有一些指针

foreach ($video->entry as $videoinfo){ 

    echo '<h2>'.$videoinfo->title.'</h2><br>'; 
    echo '<p>'.$videoinfo->content.'<br>'; 
    echo $videoinfo->link.'<br></p>'; 
    } 

感谢您的帮助

Answer 1

如果您深入了解xml（您仍然可以通过这种方式获取标题和说明），可以进入链接。

foreach ($video -> entry as $videoinfo){ 
    $mediaElem = $videoinfo -> children('media', true); 

    echo '<h2>' . $mediaElem -> group -> title . '</h2>'; 
    echo '<p'> . $mediaElem -> group -> description . '<br>'; 
    echo "<a href='" . $mediaElem -> group -> player -> attributes() -> url . "'>Watch on YouTube</a></p>" 
}
