소개

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

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.

RegexIterator::accept — Get accept status
RegexIterator::__construct — Create a new RegexIterator
RegexIterator::getFlags — Get flags
RegexIterator::getMode — Returns operation mode.
RegexIterator::getPregFlags — Returns the regular expression flags.
RegexIterator::getRegex — Returns current regular expression
RegexIterator::setFlags — Sets the flags.
RegexIterator::setMode — Sets the operation mode.
RegexIterator::setPregFlags — Sets the regular expression flags.

An exemple :





<?php


$a = new ArrayIterator(array('test1', 'test2', 'test3'));


$i = new RegexIterator($a, '/^(test)(\d+)/', RegexIterator::REPLACE);


$i->replacement = '$2:$1';


       


print_r(iterator_to_array($i));


/*


Array


(


    [0] => 1:test


    [1] => 2:test


    [2] => 3:test


)


*/


?>
