Get Wordpress post terms

gistfile1.txt

// wp_get_object_terms() always queries the database
/* If you’re looping over WP_Query results, you should prefer get_the_terms() instead.
It’s pretty much the same for most use cases, but it uses the object cache, 
which by default gets populated with the terms for the posts matching your query — unless you specifically 
set update_post_term_cache as false when instantiating WP_Query.
