I am writing php code, combining html and php for wordpress templates. The problem is that the formatter is not working well, adding other spaces.
Screenshots

Platform and version
macOS High Sierra and Intelephense version 1.3.5
I'm seeing the same thing:

This has happened before: https://github.com/bmewburn/vscode-intelephense/issues/406
macOS Mojave, Intelephense 1.3.5
<?php if ($products_most_viewed->have_posts()) : ?>
<!-- @start Products-->
<section class="mb-4 wow fadeInUp">
<div class="container">
<h2 class="c-text-subtitle mb-3 text-center text-md-left">Productos m谩s vistos</h2>
<div class="row justify-content-center">
<?php while ($products_most_viewed->have_posts()) : ?>
<div class="col-6 col-lg-3 u-xs370-force-col-full-width">
<?php
$products_most_viewed->the_post();
get_template_part('partials/product', 'card');
?>
</div>
<?php endwhile; ?>
</div>
</div>
</section>
<!-- @end Products-->
<?php endif; ?>
<?php wp_reset_postdata(); ?>
I have the same problem. Since version 1.3, only bugs appear. Please test your plugin more before releasing it. Due to bugs, i dropped the idea of buying a license.
OS : VSCode running in Windows 10 64bit using RemoteSSH in Ubuntu 18.04.3 LTS Server edition.

Screenshots are not really helpful. What is helpful are code snippets that can be debugged.
Sure thing! Here's the snippet from mine:
<div id="footer-company">
<p class="title">Company</p>
<?php wp_nav_menu(array(
'menu' => 72,
)); ?>
<?php if (!empty(get_field('twitter', 'options'))) { ?>
<p class="title">Follow us</p>
<?php } ?>
<?php require('blocks/standard/social-links/social-links.php'); ?>
I can confirm this, and I've done some troubleshooting to isolate when it happens, following code snippet I've prepared contains when it works and when it starts indenting unreasonably much.
<html>
<head>
<?php
echo "It works";
?>
<title>
<?= "I'm just here for show" ?> - <?= "I am the cause of this" ?>
</title>
<?php
echo "It does not work";
?>
</head>
</html>
I hope it's easily fixed since it causes quite an annoyance ^^
On the other hand, there is another small error when one puts html in a php function. For example: Here in the image you can see that the last function is not aligned.

This is the code
function render_menu_header($menu_header)
{
$menu_header_parent_elements = get_hierarchy_childs($menu_header, 0); // Elementos padre del menu
foreach ($menu_header_parent_elements as $item_parent) {
$item_parent_id = $item_parent['id'];
$item_parent_title = $item_parent['title'];
$item_parent_url = $item_parent['url'];
$item_parent_isactive = check_menu_active($item_parent_url);
$menu_child_elements = get_hierarchy_childs($menu_header, $item_parent_id);
?>
<li>
<a class="c-header__nav-link text-uppercase <?php echo $item_parent_isactive; ?>" href="<?php echo $item_parent_url; ?>">
<?php echo $item_parent_title; ?>
</a>
<?php if ($menu_child_elements) { ?>
<ul class="c-header__subnav">
<?php
foreach ($menu_child_elements as $item_child) {
$item_child_url = $item_child['url'];
$item_child_title = $item_child['title'];
$item_child_isactive = check_menu_active($item_child_url);
?>
<li>
<a class="c-header__subnav-link <?php echo $item_child_isactive; ?>" href="<?php echo $item_child_url; ?>">
<?php echo $item_child_title; ?>
</a>
</li>
<?php } ?>
</ul>
<?php } ?>
</li>
<?php
}
}
function qwrqeq()
{
echo '0asdasdsad';
}
When one minimizes the code blocks by visual studio code, the first function literally absorbs the second.

Confirming Bug. Formatting is buggy.
Code Sample:
<?php
echo "text";
?>
<?php if (1) : ?>
<li><a href=""><span></span><span><?php echo "hi" ?></span></a></li>
<?php endif ?>
<?php if (1) : ?>
<?php
if ((true === false)) {
}
?>
<?php endif ?>
After Formating:
<?php
echo "text";
?>
<?php if (1) : ?>
<li><a href=""><span></span><span><?php echo "hi" ?></span></a></li>
<?php endif ?>
<?php if (1) : ?>
<?php
if ((true === false)) {
}
?>
<?php endif ?>
I have the same issue, I found something that maybe can help
Bug here:

<div class="col-12 mb-5">
<nav aria-label="breadcrumb">
<ol class="breadcrumb text-uppercase mt-5 mb-0 breadcrumbBackColor">
<li class="breadcrumb-item"><a href="<?php echo $blog['dominio']; ?>" class="color-link"><i class="fas fa-home icon"></i> Inicio</a></li>
<li class="breadcrumb-item active" aria-current="page">
<?php
echo $post['titulo_post'];
?>
</li>
</ol>
</nav>
</div>
But if I put the previous echo in other line the problem goes off:

<div class="col-12 mb-5">
<nav aria-label="breadcrumb">
<ol class="breadcrumb text-uppercase mt-5 mb-0 breadcrumbBackColor">
<li class="breadcrumb-item"><a href="
<?php echo $blog['dominio']; ?>" class="color-link"><i class="fas fa-home icon"></i> Inicio</a></li>
<li class="breadcrumb-item active" aria-current="page">
<?php
echo $post['titulo_post'];
?>
</li>
</ol>
</nav>
</div>
Thanks for the examples and patience. Should be good now in 1.3.6.
