它只显示日期01.01.1970我无法得到日期并将其与今天的日期进行比较 ------------- 我想要抓取的页面的一部分

答案 0 :(得分：1)
经过一些编辑后，我们发现需要解析HTML标记的真正相关结构：
<h3><a >NETWORK SECURITY & PENTESTING</a></h3>
<div class="excerpt"><p>In the last decade, wireless networks gained a substantial momentum. One of the most beneficial features of wireless networks is […]</p>
<div class="applied date_applied">
18 July 2015
-
09 August 2015
</div>
<div class="applied date_applied">
ICT Courses
</div>
</div>
然后更清楚的是，包含两个日期的applied date_applied元素是<h3>的第一个兄弟的子元素。然后，您可以使用next_sibling()和children()一起访问它，并使用数组索引[1]来引用正确的子节点。
foreach ($html1->find('div.text h3') as $e) {
// get the two dates as an array
// The second child node of the first sibling to the <h3>
$date_array = explode('-' , trim($e->next_sibling()->children()[1]->plaintext)); $originalDate = trim($date_array[1]);
// Trim and convert them to dates:
foreach ($date_array as &$d) {
$d = strtotime(trim($d));
}
}
检查结果（现在全部转换为时间戳）：
print_r($date_array);
