Exemple #1 RegexIterator::setPregFlags() example

Creates a new RegexIterator that filters all entries with where the array key starts with 'test'.

`<?php
$test = array ('test 1', 'another test', 'test 123');
$arrayIterator = new ArrayIterator($test);
$regexIterator = new RegexIterator($arrayIterator, '/^test/', RegexIterator::GET_MATCH);
$regexIterator->setPregFlags(PREG_OFFSET_CAPTURE);
foreach ($regexIterator as $key => $value) {
var_dump($value);
}
?>`

L'exemple ci-dessus va afficher quelque chose de similaire à :

    array(1) {
      [0]=>
      array(2) {
        [0]=>
        string(4) "test"
        [1]=>
        int(0)
      }
    }
    array(1) {
      [0]=>
      array(2) {
        [0]=>
        string(4) "test"
        [1]=>
        int(0)
      }
    }
