(PHP 5 >= 5.2.0)

RegexIterator::setPregFlags — Sets the regular expression flags.

### Description

public void RegexIterator::setPregFlags ( int `$preg_flags` )

Sets the regular expression flags.

### Parameters

`preg_flags`

  The regular expression flags. See RegexIterator::__construct() for an overview of available flags.

### Return Values

No value is returned.

### Examples

Example #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);
}
?>`

The above example will output something similar to:

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