Then the terms are passed through a double-layered array_map() construction. The inner array_map() extracts the term names from the……terms (get_the_terms() returns full WP_Term objects, but we only care about the name) – it’s just a version of array_column() for objects, basically. The outer array_map() passes the terms through a callback function, depending on which behaviour is required. The default mode is restrict_to_taxonomy, which adds phrases and the taxonomy targeting,…
