RegexIterator operation modes

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 (see preg_replace(); Not fully implemented yet)
