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";
}
?>
