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.
RegexIterator::INVERT_MATCH: Inverts the return value of RegexIterator::accept().

属性

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

)

*/

?>
