重新加载DIV而不重新加载整个页面

我有一个Wordpress主题，它的页脚有一个粘性音频播放器，正在播放Shoutcast电台。

我从另一个PHP文件将歌曲艺术家/标题的详细信息调用到粘性条中，它显示得很好，但从未更新。我只需要这个文本内容每10秒重新加载一次，而不需要重新加载整个网页。

有人能告诉我怎么做吗？提前感谢您。

这是具有音频播放器的主题中的PHP文件的代码：

（radio player.php）

<?php 
$radio_ip = get_option('atp_radiostream_id');
$radio_autoplay = get_option('atp_radio_autoplay');
$radio_title = get_option('atp_radio_title');
$radio_desc = get_option('atp_radio_desc');
$atp_playlist_volume = get_option( 'atp_playlist_volume' )  ? get_option( 'atp_playlist_volume' ) : '0.6';
?>
<script type="text/javascript">
jQuery(document).ready(function($){
    var stream = {
        mp3: "<?php echo $radio_ip; ?>"

        ready: function (event) {
            ready = true;
