(PHP 5 >= 5.2.0)

Introdução

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

Sinopse da classe

RegexIterator extends FilterIterator {
/* Constantes */
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 ;
/* Métodos */

public int getPregFlags ( void )
public string getRegex ( void )
public void setFlags ( int $flags )
public void setMode ( int $mode )

Constantes pré-definidas

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)

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
)
*/
?>
