我想获取值，例如标题、日期和 URL。我可以轻松检索标题和日期，PHP 代码是：

<?php foreach($entries['items'] as $entry)  { ?>
Title: <?php echo $entry->title; ?>
Date: <?php echo date("M d Y",strtotime($entry->pubDate)); ?>
URL: <?php echo $entry->url ?>
<?php } ?>

但是我无法在这里获取URL的值，我该如何获取呢？

您可以使用attributes()方法获得它。

$attrs = $entry->enclosure->attributes();
echo $attrs['url'];
