经过一些编辑，我们找到了需要解析的 HTML 标记的真实相关结构：

<h3><a >NETWORK SECURITY &amp; 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>

那么包含两个日期的 applied date_applied 元素是 <h3> 第一个兄弟元素的子元素就变得更清楚了。然后，您可以使用 next_sibling() 和 children() 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));
  }
}

检查您的结果（现在全部转换为时间戳）：

print_r($date_array);
Array
(
    [0] => 1437195600
    [1] => 1439096400
)
Array
(
    [0] => 1437973200
    [1] => 1440565200
)
Array
(
    [0] => 1437973200
    [1] => 1442552400
)
Array
(
    [0] => 1438059600
    [1] => 1442638800
)
