   The difference between this function and get_the_terms() is that this function’s results are not cached (thus, it’ll hit the database every time its called).

   • This is not entirely true. Another key distinction is that get_the_terms() does not allow the third parameter: $args.

   You can get the taxonomy terms HTML using this function am_get_post_term

   function am_get_post_terms( $post_id = 0, $taxonomy = 'category', $custom_html = ['ul','li','a'] ) {	$post_terms = wp_get_post_terms( $post_id, $taxonomy );	$custom_html[0] = isset($custom_html[0]) ? $custom_html[0] : 'ul';	$custom_html[1] = isset($custom_html[1]) ? $custom_html[1] : 'li';	$custom_html[2] = isset($custom_html[2]) ? $custom_html[2] : 'a';	$post_term_html = '';	$post_term_html .= '<' . $custom_html[0] . '>';	foreach( $post_terms as $p_term ) {	$post_term_html .= '<' . $custom_html[1] . '><' . $custom_html[2] . ' href="'. get_term_link( $p_term->term_id, $taxonomy ) .'">'. $p_term->name .'</' . $custom_html[2] . '></' . $custom_html[1] . '>';	}	$post_term_html .= '</' . $custom_html[0] . '>';	return $post_term_html; } Call the function in single.php file work for all CPT: 
   echo am_get_post_terms( get_the_ID(), 'category',['div','span','a'] );
