array_keys() · Return all the keys of an array, or only the keys whose value matches a search value.
array_filter() · Keep only the elements for which a callback returns true. Without a callback it removes empty values; keys are kept.
array_is_list() · Check whether an array's keys are 0, 1, 2… in order, so it would encode as a JSON array. Added in PHP 8.1.
