PHP将HTML字符串拆分为数组 [英] PHP Split html string into array

问题描述

我希望我能从你们那里得到一些帮助。

I hope I can get some help from you guys.

这就是我正在努力解决的问题，
我有一串HTML，看起来像这样：

This is what I'm struggling with, I have a string of HTML that will look like this:

<h4>Some title here</h4>
<p>Lorem ipsum dolor</p>
(some other HTML here)

<h4>Some other title here</h4>
<p>Lorem ipsum dolor</p>
(some other HTML here)

我需要拆分所有< h4> 从其余内容开始，例如第一个< h4> 之后和第二个< h4> 需要与第一个< h4> 相关，例如：

I need to split all the <h4> from the rest of the content, but for example the content after the first <h4> and before the second <h4> needs to be related to the first <h4>, something like this:

Array {
       [0] => <h4>Some title here</h4>
       [1] => <p>Lorem ipsum dolor</p>
}

Array {
       [0] => <h4>Some other title here</h4>
       [1] => <p>Lorem ipsum dolor</p>
}

这是建造一架手风琴（很难解释为什么我在做这样，但必须是这种方式），< h4> 将成为手风琴面板的标题，并且在单击时将展开并显示与它们相关的内容

This is to build an accordion (quite difficult to explain why I'm doing this way, but it has to be this way), and the <h4> will be the accordion panel headings and when clicked it will expand and show the content associated with them.

我希望我能明确说明我的问题，让我知道您的想法，以及如何更好地做到这一点。

I hope I made my problem clear, let me know of your thoughts and how should I do this the better way.

我一直在研究 DOMDocument ，但是我也尝试了 explode（），但没有成功。

I was looking into DOMDocument, but I also tried with explode() but with no success.

我有使用JavaScript的方法，但是我需要用PHP实现相同的功能，但是使用DOM和PHP进行操作相当复杂。

I have this working with JavaScript but I need to achieve the same thing with PHP, but it's quite complicated to play with the DOM with PHP.

谢谢。

推荐答案

我能够按照<一个href = https://stackoverflow.com/questions/18156164/parse-html-and-get-all-h3s-after-an-h2-before-the-next-h2-using-php>示例 Derek S 给了我。

结果是：

$html_string = 'HTML string';
$dom = new DOMDocument();
$dom->loadHTML($html_string);

foreach($dom->getElementsByTagName('h4') as $node) {
   $title = $dom->saveHTML($node);
   $content[$title] = array();

   while(($node = $node->nextSibling) && $node->nodeName !== 'h4') {
      $content[$title] = $dom->saveHTML($node);
   }
}

这会将标题保存在 $ title 以及 $ content [$ title] 中的对应内容。

This will save the titles inside $title and the correspondent content inside $content[$title].
