Introdução

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

Sinopse da classe

class RegexIterator extends FilterIterator {
/* Constantes */
const int MATCH = 0;
const int GET_MATCH = 1;
const int ALL_MATCHES = 2;
const int SPLIT = 3;
const int REPLACE = 4;
const int USE_KEY = 1;
/* Métodos */
public __construct(
    Iterator $iterator,
    string $pattern,
    int $mode = RegexIterator::MATCH,
    int $flags = 0,
    int $pregFlags = 0
)
public accept(): bool
public getFlags(): int
public getMode(): int
public getPregFlags(): int
public getRegex(): string
public setFlags(int $flags): void
public setMode(int $mode): void
public setPregFlags(int $pregFlags): void
/* Métodos herdados */
public FilterIterator::accept(): bool
}

Constantes pré-definidas

RegexIterator operation modes

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
)
*/
?>
