Example #1 NoRewindIterator::__construct() example

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:
