<?php
    private function buildPatternsAndReplacementsFromMap(array $map, string $direction): array
    {
        $finalMap = $map;
        if ($direction === self::DIRECTION_RTL) {
            $finalMap = array_flip($map);
        }

        $patterns = array_map(
            function (string $wordOrPhrase): string {
                return sprintf('/\b%s\b/ui', $wordOrPhrase);
            },
            array_keys($finalMap)

It seems like $finalMap can also be of type null; however, parameter $input of array_keys() does only seem to accept array, maybe add an additional type check?

        );
        $replacements = array_values($finalMap);

        return [$patterns, $replacements];

The expression return array($patterns, $replacements) returns the type array<integer,array> which is incompatible with the documented return type string[].
