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)
RegexIterator::SPLIT- Returns the split values for the current entry (see preg_split()).
RegexIterator Flags
RegexIterator::USE_KEY- Special flag: Match the entry key instead of the entry value.
