How to check the body tag if it has a class name of “single-product” using php?

I need an if statement that checks the body tag if it has a class name of “single-product” using php? I need to echo a function in a single product page only of woocommerce of wordpress.

This is the code that I would like to show only for single product pages that uses woocommerce.php

<div id="from_product_page">
  <?php 
  $recent = new WP_Query("page_id=235"); 
  while($recent->have_posts()) : $recent->the_post();?>
    <?php the_title(); ?>
    <?php the_content(); ?>
  <?php endwhile; ?>
</div>

  1. PHP can’t detect the body tag class of the current page, but you could use javascript or jquery to detect it and then trigger an ajax call to a php. You may be to use a client-server-client sequence.

    <script>
    if ( $('body').hasClass('single-product') ) { 
        $('#some_input').val('single-product');
    }
    
    $.getJSON( 'gAjax.php?whatever=' + $('#whatever').val(), null, function(jdata) {
    
    var jObj = $.parseJSON(jdata);  //RETURNED DATA
    
    ...    
    <script>
