The RegexIterator class

Einführung

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

Klassenbeschreibung

RegexIterator extends FilterIterator {
/* Konstanten */
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 ;
/* Methoden */
__construct ( Iterator $iterator , string $regex [, int $mode [, int $flags [, int $preg_flags ]]] )
public bool accept ( void )
public int getFlags ( void )
public int getMode ( void )
public int getPregFlags ( void )
public void setFlags ( int $flags )
public void setMode ( int $mode )
public void setPregFlags ( int $preg_flags )
/* Geerbte Methoden */
abstract bool FilterIterator::accept ( void )
FilterIterator::__construct ( Iterator $iterator )
mixed FilterIterator::current ( void )
Iterator FilterIterator::getInnerIterator ( void )
mixed FilterIterator::key ( void )
void FilterIterator::next ( void )
void FilterIterator::rewind ( void )
bool FilterIterator::valid ( void )
}

Vordefinierte Konstanten

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.

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
)
*/
?>
