我想获得价值，比如Title，Date＆amp; 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 } ?>

但我无法在此获得网址的价值，我该怎么做？

答案 0 :(得分：1)

您可以使用attributes()方法获取它。

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