RegexIterator::ALL_MATCHES: Return all matches for the current entry (see preg_match_all()).
RegexIterator::GET_MATCH: Return the first match for the current entry (see preg_match()).
RegexIterator::MATCH: Only execute match (filter) for the current entry (see preg_match()).
RegexIterator::REPLACE: Replace the current entry or the current key (see preg_replace()).
RegexIterator::SPLIT: Returns the split values for the current entry (see preg_split()).

RegexIterator::USE_KEY: Special flag: Match the entry key instead of the entry value.
