 * In my single.php file I am trying to list all the child categories under a specific
   parent category. I’m using the following code:
 *     ```
       if(!function_exists('subcat')){
       	function subcat(){
       		global $post;
       foreach((get_the_category()) as $category)
       {
           if ($category->category_parent == "177")
           {
               echo '<a href="' . get_category_link($category->cat_ID) . '">' . $category->cat_name . '</a>';
           }
       }
       	}
       }
       ```
   
 * The code works, but in instances where there are multiple subcategories I would
   like to separate those subcategories with a comma. How do I do that? Anyone know?

 * This should work:
 * replace this
    `if ($category->category_parent == "177")`
 * with this
 *     ```
       $cats = array(177, 213, 309);
       if ( in_array( $category->category_parent, $cats ) ) {
       ```
   
 * if you have one category you can either use
    `if ($category->category_parent 
   == "177")` or
 *     ```
       $cats = array(177);
       if ( in_array( $category->category_parent, $cats ) ) {
       ```

 * Thank you. I actually figured out an alternative using css. 🙂
