How to sort Joomla content output by ID?

Question

Joomla

People, please tell me how to rewrite the output of the module so that the materials are sorted by category ID?
Here is the output code

<?php for ($i = 0, $n = count($list); $i < $n; $i ++) : ?>
<?php $item = $list[$i]; ?>
<div class="item">
<?php require JModuleHelper::getLayoutPath('mod_articles_news', '_item'); ?>

<?php if ($n > 1 && (($i < $n - 1) || $params->get('showLastSeparator'))) : ?>
<span class="article-separator"> </span>
<?php endif; ?>
</div>
<?php endfor; ?>

This variable contains the category ID.
$item->catid
You need to build the output in ascending order of category IDs. Google says to use the Array() function, but I don't have enough knowledge!((
