Can’t include js files in php file on cpanel

I am trying to use a JavaScript library (from GitHub) on my website but I can’t get it to work. It works when I set it up in VS code but not when I upload my code to cpanel (along with the required files). The website is a wordpress site so I just create page templates and link the templates to the specific pages. I have uploaded all of the code and files correctly and this is how I have tried to include them:

#particles-js{
  position: relative;
  z-index: 1;
  background-color: #000;
  min-height: 100vh;
  min-width: 100vw;
}

<div id="particles-js"></div>

<script src="/home/fittecha/repositories/particles.js/particles.js"></script>
<script src="/home/fittecha/repositories/particles.js/particles.min.js"></script>
<script src="/home/fittecha/repositories/particles.js/demo/js/app.js"></script>

I also tried using <?php include '/home/fittecha/repositories/particles.js/demo/js/app.js'; ?> etc, but that didn’t work either. Please advise.

Answer

I managed to sort it out. I changed the html to a php include function and placed it at the bottom of my document:

<script>
      <?php
        include '/home/fittecha/repositories/particles.js/particles.js';
        include '/home/fittecha/repositories/particles.js/particles.min.js';
        include '/home/fittecha/repositories/particles.js/demo/js/app.js';

      ?>
 </script>

I am not sure why this didn’t work before when I tried it but it’s all working now
