php - Tumblr 到网站的这个 XML/PHP 代码有问题吗？

Question

我正在尝试将 tumblr 提要链接到网站。我找到了这段代码（如您所见，它必须被破坏，因为它在这篇文章中甚至没有正确格式化）：

    <?php
$request_url = “http://thewalkingtree.tumblr.com/api/read?type=post&start=0&num=1”;
$xml = simplexml_load_file($request_url);
$title = $xml->posts->post->{‘regular-title’};
$post = $xml->posts->post->{‘regular-body’};
$link = $xml->posts->post[‘url’];
$small_post = substr($post,0,320);
echo ‘&lt;h1>’.$title.’&lt;/h1>’;
echo ‘&lt;p>’.$small_post.’&lt;/p>’;
echo “…”;
echo “&lt;/br><a target=frame2 href=’”.$link.”’&gt;Read More</a>”; 
?>

And i inserted the tumblr link that I will be using.  When I try to preview my HTML, i get a bunch of messed up code that reads as follows:

posts->post->{'regular-title'}; $post = $xml->posts->post->{'regular-body'}; $link = $xml->posts->post['url']; $small_post = substr($post,0,320); echo '
'.$title.'

'; echo '
'.$small_post.'

'; echo "…"; echo "Read More"; ?>

任何帮助，将不胜感激。谢谢！

那是 PHP，不是 HTML。在将其传送到 Web 浏览器之前，您需要使用 PHP 解析器对其进行处理。

…它也应该被重写，以便它可以缓存远程数据，并在将数据注入 HTML 文档之前转义特殊字符。
