I am using Opigno (a LMS based on drupal) and I want to edit a page. I am looking for its HTML but when I open the code for the page this is what I found.
<?php print render($page['content']); <?php print render($page['content_bottom']); ?>
I try to use print_r function in PHP and it displays an array of stuff.
How could I change the page if it is from php.
