due to debugging and error hunting in a plugin, I have a quick question.
What does $wpdb->get_row() return in case there are no results? The documentation says:
(array|object|null|void) Database query result in format specified by $output or null on failure.
But when looking at the source code, it rather seems like it returns "null"…
A quick help would be appreciated, I always thought that it returns an empty array but I might be mistaken!
