SimplePie 可以从提要中抓取图像吗

Okay i am sorry, i am new at this. I am just using the code straight from the website to try and view the blog. i will put the code at the bottom here. So yea like i said i'm just trying to get the images to show up that are on the blog i'm reading from. Everything shows up great except that.

<?php

// Make sure SimplePie is included. You may need to change this to match the location of simplepie.inc.
require_once('simplepie.inc');

// We'll process this feed with all of the default options.
$feed = new SimplePie();

// Set the feed to process.
$feed->set_feed_url('http://wordpress.homickdesign.com/feed/');

// Run SimplePie.
$feed->init();

// This makes sure that the content is sent to the browser as text/html and the UTF-8 character set (since we didn't change it).
$feed->handle_content_type();

// Let's begin our XHTML webpage code.  The DOCTYPE is supposed to be the very first thing, so we'll keep it on the same line as the closing-PHP tag.
?>

<h2><a href="<?php echo $feed->get_permalink(); ?>"><?php echo $feed->get_description(); ?></a><br />
      <span>Latest news from Robert Homick</span></h2>       

        <?php
$c=1;   
foreach ($feed->get_items() as $item):
if($c <= 3){
?>

        <p><a href="<?php echo $item->get_permalink(); ?>"><?php echo $item->get_title(); ?></a><br />
        <?php echo $item->get_description(); ?><br />
        <span>Posted on <?php echo $item->get_date('j F Y | g:i a'); ?></span><br />
        <?php $c++;?>


<?php } endforeach;  ?>

推荐答案

是的，您可以调用 get_content() 并将整个帖子或包含在提要中的帖子部分输出到屏幕上，所有包括 HTML 标签.如果你想拉出帖子中的第一张图片，你必须做更多的工作，这是我一直在做的.

$htmlDOM = new simple_html_dom();
$htmlDOM->load($item->get_content());
$image = $htmlDOM->find('img', 0); 
$html .= '<img src="thumbnail.php?file=' . $image->src . '&maxw=300&maxh=300" border="0" />';
