预定义常量

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.
