我有一个下面的代码可以正常工作但缺少一件事。它没有返回$item['link']哪个是href标题的值。

include('simple_html_dom.php');
$html = file_get_html('http://news.google.com/news/section?pz=1&cf=all&ned=us&q=newzealand'); 


foreach($html->find('.blended-wrapper') as $article) {
    $item['title']     = $article->find('span.titletext', 0)->plaintext;
    $item['source']    = $article->find('span.esc-lead-article-source', 0)->plaintext;
    $item['clip'] = $article->find('div.esc-lead-snippet-wrapper', 0)->plaintext;

    $item['link'] = $article->find('.esc-lead-article-title a')->href;

    $articles[] = $item;
}

echo "<pre>";
print_r($articles);
echo "<pre/>";

这就是它输出的内容，因为您看到链接键是空的。我已经尝试了很多东西。大批

您必须获得第一个链接，即使集合中只有一个：

$item['link'] = $article->find('.esc-lead-article-title a', 0)->href;

尽管 simple_html_dom 是根据 jQuery 建模的，但它的 API 并不完全映射到 jQuery。
