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:

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

array(2) {

}
}
