The second loop does not output because the iterator is only used once,
as it does not rewind.
<?php
$fruit = array('apple', 'banana', 'cranberry');
$arr = new ArrayObject($fruit);
$it = new NoRewindIterator($arr->getIterator());
echo "Fruit A:\n";
foreach( $it as $item ) {
echo $item . "\n";
}
echo "Fruit B:\n";
foreach( $it as $item ) {
echo $item . "\n";
}
?>
The above example will output
something similar to:
Fruit A:
apple
banana
cranberry
Fruit B:
