How to convert html to formatted text in php?

Question

PHP

There is text in html markup with paragraphs, lists, and so on. How can php convert it to plain formatted text for saving as txt?
For example, there is a type:

<p>абзац 1</p>
<p>абзац 2</p>
<ul>
  <li>пункт 1</li>
  <li>пункт 2</li>
  <li>пункт 3</li>
</ul>

You need to make it look like:

paragraph 1
paragraph 2
- paragraph 1 - paragraph
2 - paragraph
3

Answer 1

So?

$txt = str_replace('<li', '-<li', $txt); // добавим минусы в списке
$txt = strip_tags($txt); // уберем теги

$rows = explode("\n", $txt); // разобьем на строки
$rows = array_map('trim', $rows); // уберем пробелы в начале и конце
$rows = array_filter($rows); // уберем пустые строки

echo implode("\n", $rows);  // склеим строки снова в текст

There are also ready-made libraries, such as this

Usually they use this: https://www.php.net/manual/ru/book.pcre.php - welcome to Hell =)
But personally, I would look for some kind of library on Github - there are probably many such packages.
