 * I have a very basic function that echoes the Category ID
 *     ```
       <?php
       function get_cat_id_now() {
       	$category = get_the_category();
       	$thecatid = $category[0]->cat_ID;
       	echo $thecatid;
       }
       ?>
       ```
   
 * and then, I want to use the include function together with the get_cat_id_now
   function.
    Like this: `<?php include("/related/".get_cat_id_now().".html"); ?
   >`
 * But it doesn’t work.
    How do I add the `get_cat_id_now()` correctly into the `
   include(/related/function_goes_here.html")` ?

    getting the cat
   id

 * Don’t echo $thecatid, return it.
