The RegexIterator class

(PHP 5 >= 5.2.0, PHP 7)

��

This iterator can be used to filter another iterator based on a regular expression.

RegexIterator extends FilterIterator {

/* �� */

const integer MATCH = 0 ;

const integer GET_MATCH = 1 ;

const integer ALL_MATCHES = 2 ;

const integer SPLIT = 3 ;

const integer REPLACE = 4 ;

const integer USE_KEY = 1 ;

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