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

$arrayIterator?=?new?ArrayIterator($test);
$regexIterator?=?new?RegexIterator($arrayIterator,?'/^test/',?RegexIterator::GET_MATCH);

$regexIterator->setPregFlags(PREG_OFFSET_CAPTURE);

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