How to convert words to hash tags in Yii2?

Question

Yii

When you enter question tags on this site, you get a set of words, which is then converted into links, or so-called hash tags.
Let's say I put these words on a website page:

<div>
<?php foreach ($janre as $tab) { ?>
<?=$tab->id_j?>
<?php } ?>
</div>

I got a set of words:
<div>фантастика ужасы</div>
I wrote javascript that made these words links (hash tags)

var y;
var message = new Array();
message[1] = 'фантастика';
message[2] = 'ужасы';
//Выведем все элементы массива и заменим на ссылки
for (y in message) {
   document.body.innerHTML = document.body.innerHTML.replace(message[y], '<a href="https://vk.com/feed?q=' + message[y] + '&section=search" target="_blank">#' + message[y] + '</a> ');
}

You get something like:

<div>
<a href="https://vk.com/feed?q=фантастика&section=search" target="_blank">#фантастика</a> 
<a href="https://vk.com/feed?q=ужасы&section=search" target="_blank">#ужасы</a>
</div>

QUESTION:
How to implement all this without crutches in Yii2 with minimal code, without installing someone's development? I have a script, a database is connected, tags are entered and added to the input, all I need is a Yii implementation of hash tags, no matter how many of them the user adds.

Thank you in advance for your response, and refraining from reproaches and moralizing.
