--FILE--
<?php
class foo extends ArrayIterator {
    public function __construct( ) {
        parent::__construct(array(
            'test3'=>'test999'));
    }
}

$h = new foo;
$i = new RegexIterator($h, '/^test(.*)/', RegexIterator::REPLACE);
$i->replacement = "42";
var_dump($i->replacement);
foreach ($i as $name=>$value) {
    var_dump($name, $value);
}
var_dump($i->replacement);
?>

string(2) "42"
string(5) "test3"
